ChangeLog for previous patch: regenerate intl-auto-encap-win32.c (fix build problems when building --with-msw=no on Cygwin) -------------------- ChangeLog entries follow: -------------------- lib-src/ChangeLog addition: 2010-01-15 Ben Wing <ben@xemacs.org> * make-mswin-unicode.pl: Various fixes to get this to work when using the Cygwin header files in /usr/include/w32api instead of the VC++ ones: -- Use /usr/include/w32api as default; don't assume that a passed-in directory always ends in .../include. -- Add `const' to list of known type modifiers. -- If function already seen, warn but don't generate twice. -- Eliminate `extern' from return type modifiers. -- Cosmetic: When eliminating APIENTRY, also eliminate following whitespace. src/ChangeLog addition: 2010-01-15 Ben Wing <ben@xemacs.org> * intl-auto-encap-win32.c: * intl-auto-encap-win32.c (qxeExtractAssociatedIcon): * intl-auto-encap-win32.c (qxeShellExecuteEx): * intl-auto-encap-win32.c (qxeSHFileOperation): * intl-auto-encap-win32.c (qxeSHQueryRecycleBin): * intl-auto-encap-win32.c (qxeSHEmptyRecycleBin): * intl-auto-encap-win32.c (qxeWNetAddConnection): * intl-auto-encap-win32.c (qxeWNetAddConnection2): * intl-auto-encap-win32.c (qxeWNetAddConnection3): * intl-auto-encap-win32.c (qxeWNetCancelConnection): * intl-auto-encap-win32.c (qxeWNetCancelConnection2): * intl-auto-encap-win32.c (qxeWNetGetConnection): * intl-auto-encap-win32.c (qxeWNetUseConnection): * intl-auto-encap-win32.c (qxeWNetConnectionDialog1): * intl-auto-encap-win32.c (qxeWNetDisconnectDialog1): * intl-auto-encap-win32.c (qxeWNetOpenEnum): * intl-auto-encap-win32.c (qxeWNetEnumResource): * intl-auto-encap-win32.c (qxeWNetGetUniversalName): * intl-auto-encap-win32.c (qxeWNetGetUser): * intl-auto-encap-win32.c (qxeWNetGetProviderName): * intl-auto-encap-win32.c (qxeWNetGetNetworkInformation): * intl-auto-encap-win32.c (qxeWNetGetLastError): * intl-auto-encap-win32.c (qxeMultinetGetConnectionPerformance): * intl-auto-encap-win32.c (qxeAppendMenu): * intl-auto-encap-win32.c (qxeCopyAcceleratorTable): * intl-auto-encap-win32.c (qxeDlgDirSelectComboBoxEx): * intl-auto-encap-win32.c (qxeEnumDesktops): * intl-auto-encap-win32.c (qxeEnumWindowStations): * intl-auto-encap-win32.c (qxeGetClassInfo): * intl-auto-encap-win32.c (qxeGetClassLong): * intl-auto-encap-win32.c (qxeGetClassName): * intl-auto-encap-win32.c (qxeGetKeyboardLayoutName): * intl-auto-encap-win32.c (qxeGetWindowLong): * intl-auto-encap-win32.c (qxeGetUserObjectInformation): * intl-auto-encap-win32.c (qxeGetWindowTextLength): * intl-auto-encap-win32.c (qxeGrayString): * intl-auto-encap-win32.c (qxeInsertMenu): * intl-auto-encap-win32.c (qxeSetProp): * intl-auto-encap-win32.c (qxeEnumICMProfiles): * intl-auto-encap-win32.c (qxeExtTextOut): * intl-auto-encap-win32.c (qxeSetICMProfile): * intl-auto-encap-win32.c (qxeTextOut): * intl-auto-encap-win32.c (qxeSHGetPathFromIDList): * intl-auto-encap-win32.c (qxeFindText): * intl-auto-encap-win32.c (qxeReplaceText): * intl-auto-encap-win32.c (qxeImmInstallIME): * intl-auto-encap-win32.c (qxeImmGetDescription): * intl-auto-encap-win32.c (qxeImmGetIMEFileName): * intl-auto-encap-win32.c (qxeImmGetCompositionString): * intl-auto-encap-win32.c (qxeImmGetCandidateListCount): * intl-auto-encap-win32.c (qxeImmGetCandidateList): * intl-auto-encap-win32.c (qxeImmGetGuideLine): * intl-auto-encap-win32.c (qxeImmConfigureIME): * intl-auto-encap-win32.c (qxeImmEscape): * intl-auto-encap-win32.c (qxeImmGetConversionList): * intl-auto-encap-win32.c (qxeImmRegisterWord): * intl-auto-encap-win32.c (qxeImmUnregisterWord): * intl-auto-encap-win32.c (qxeImmEnumRegisterWord): * intl-auto-encap-win32.c (qxesndPlaySound): * intl-auto-encap-win32.c (qxePlaySound): * intl-auto-encap-win32.c (qxewaveOutGetErrorText): * intl-auto-encap-win32.c (qxewaveInGetErrorText): * intl-auto-encap-win32.c (qxemidiOutGetErrorText): * intl-auto-encap-win32.c (qxemidiInGetErrorText): * intl-auto-encap-win32.c (qxemmioStringToFOURCC): * intl-auto-encap-win32.c (qxemmioInstallIOProc): * intl-auto-encap-win32.c (qxemmioOpen): * intl-auto-encap-win32.c (qxemmioRename): * intl-auto-encap-win32.c (qxemciSendCommand): * intl-auto-encap-win32.c (qxemciSendString): * intl-auto-encap-win32.c (qxemciGetDeviceID): * intl-auto-encap-win32.c (qxemciGetErrorString): * intl-auto-encap-win32.h: * intl-auto-encap-win32.h (qxemciGetErrorString): Regenerate these files from Cygwin headers. * intl-encap-win32.c: Bracket more functions in HAVE_MS_WINDOWS, to fix build problems when building --with-msw=no on Cygwin. Fixes for Cygwin headers: -- Comment out IME.H, non-existent in Cygwin. -- Make MessageBoxIndirect a `no' (don't encapsulate but generate error if used) because it has a structure parameter that needs to be A/W split but is declared as FOO*, and our parser can't split this.
