Avoid EOVERFLOW from stat() calls due to overflowing inode numbers.
The btrfs filesystem now uses 64-bit inode numbers even on 32-bit systems.
This can lead to spurious stat() failures, where EOVERFLOW is returned because
the inode number does not fit into the 32-bit stat structure, even when the
caller is not interested in the inode number. This patch builds with
_FILE_OFFSET_BITS == 64 when possible, and deals with integers that may be
too large to fit into a Lisp fixnum. For more information, see xemacs-patches

| 442 displaying "XEmacs". | |
| 443 | |
| 444 Possible flags are | |
| 445 | |
| 446 | |
| 447 -- To specify the buttons in the message box: | |
| 448 | |
| 449 abortretryignore | |
| 450 The message box contains three push buttons: Abort, Retry, and Ignore. | |
| 451 ok | |
| 452 The message box contains one push button: OK. This is the default. | |
| 453 okcancel | |
| 454 The message box contains two push buttons: OK and Cancel. | |
| 455 retrycancel | |
| 456 The message box contains two push buttons: Retry and Cancel. | |
| 457 yesno | |
| 458 The message box contains two push buttons: Yes and No. | |
| 459 yesnocancel | |
| 460 The message box contains three push buttons: Yes, No, and Cancel. | |
| 461 | |
| 462 | |
| 463 -- To display an icon in the message box: | |
| 464 | |
| 465 iconexclamation, iconwarning | |
| 466 An exclamation-point icon appears in the message box. | |
| 467 iconinformation, iconasterisk | |
| 468 An icon consisting of a lowercase letter i in a circle appears in | |
| 469 the message box. | |
| 470 iconquestion | |
| 471 A question-mark icon appears in the message box. | |
| 472 iconstop, iconerror, iconhand | |
| 473 A stop-sign icon appears in the message box. | |
| 474 | |
| 475 | |
| 476 -- To indicate the default button: | |
| 477 | |
| 478 defbutton1 | |
| 479 The first button is the default button. This is the default. | |
| 480 defbutton2 | |
| 481 The second button is the default button. | |
| 482 defbutton3 | |
| 483 The third button is the default button. | |
| 484 defbutton4 | |
| 485 The fourth button is the default button. | |
| 486 | |
| 487 | |
| 488 -- To indicate the modality of the dialog box: | |
| 489 | |
| 490 applmodal | |
| 491 The user must respond to the message box before continuing work in | |
| 492 the window identified by the hWnd parameter. However, the user can | |
| 493 move to the windows of other applications and work in those windows. | |
| 494 Depending on the hierarchy of windows in the application, the user | |
| 495 may be able to move to other windows within the application. All | |
| 496 child windows of the parent of the message box are automatically | |
| 497 disabled, but popup windows are not. This is the default. | |
| 498 systemmodal | |
| 499 Same as applmodal except that the message box has the WS_EX_TOPMOST | |
| 500 style. Use system-modal message boxes to notify the user of serious, | |
| 501 potentially damaging errors that require immediate attention (for | |
| 502 example, running out of memory). This flag has no effect on the | |
| 503 user's ability to interact with windows other than those associated | |
| 504 with hWnd. | |
| 505 taskmodal | |
| 506 Same as applmodal except that all the top-level windows belonging to | |
| 507 the current task are disabled if the hWnd parameter is NULL. Use | |
| 508 this flag when the calling application or library does not have a | |
| 509 window handle available but still needs to prevent input to other | |
| 510 windows in the current application without suspending other | |
| 511 applications. | |
| 512 | |
| 513 | |
| 514 In addition, you can specify the following flags: | |
| 515 | |
| 516 default-desktop-only | |
| 517 The desktop currently receiving input must be a default desktop; | |
| 518 otherwise, the function fails. A default desktop is one an | |
| 519 application runs on after the user has logged on. | |
| 520 help | |
| 521 Adds a Help button to the message box. Choosing the Help button or | |
| 522 pressing F1 generates a Help event. | |
| 523 right | |
| 524 The text is right-justified. | |
| 525 rtlreading | |
| 526 Displays message and caption text using right-to-left reading order | |
| 527 on Hebrew and Arabic systems. | |
| 528 setforeground | |
| 529 The message box becomes the foreground window. Internally, Windows | |
| 530 calls the SetForegroundWindow function for the message box. | |
| 531 topmost | |
| 532 The message box is created with the WS_EX_TOPMOST window style. | |
| 533 service-notification | |
| 534 Windows NT only: The caller is a service notifying the user of an | |
| 535 event. The function displays a message box on the current active | |
| 536 desktop, even if there is no user logged on to the computer. If | |
| 537 this flag is set, the hWnd parameter must be NULL. This is so the | |
| 538 message box can appear on a desktop other than the desktop | |
| 539 corresponding to the hWnd. | |
| 540 | |
| 541 | |
| 542 | |
| 543 The return value is one of the following menu-item values returned by | |
| 544 the dialog box: | |
| 545 | |
| 546 abort | |
| 547 Abort button was selected. | |
| 548 cancel | |
| 549 Cancel button was selected. | |
| 550 ignore | |
| 551 Ignore button was selected. | |
| 552 no | |
| 553 No button was selected. | |
| 554 ok | |
| 555 OK button was selected. | |
| 556 retry | |
| 557 Retry button was selected. | |
| 558 yes | |
| 559 Yes button was selected. | |
| 560 | |
| 561 If a message box has a Cancel button, the function returns the | |
| 562 `cancel' value if either the ESC key is pressed or the Cancel button | |
| 563 is selected. If the message box has no Cancel button, pressing ESC has | |
| 564 no effect. */ | |
