[xemacs-hg @ 2005-01-26 03:40:10 by ben] Puh-raise the lawd! insert-data-in-exec.c: Need to open everything as binary. Makefile.in.in: Don't compile executable as Windows (-mwindows) under Cygwin. Semi-recent changes to Cygwin's executable-startup handling make it impossible to access the TTY this way. Don't use special linker file under Cygwin (cygwin.sc) except when non-PDUMP (even in this case it is highly questionable); you get errors like 1 [main] temacs 1364 fhandler_console::fixup_after_exec: error opening input console handle after exec, errno 13, Win32 error 5 5820 [main] temacs 1364 fhandler_console::fixup_after_exec: error opening output console handle after exec, errno 13, Win32 error 5
