(ftruncate): Replace it if REPLACE_FTRUNCATE is 1. * m4/unistd_h.m4 (gl_UNISTD_H): Require gl_SYS_TYPES_H. (gl_UNISTD_H_DEFAULTS): Initialize REPLACE_FTRUNCATE. * modules/unistd (Depends-on): Add sys_types. (Makefile.am): Substitute WINDOWS_64_BIT_OFF_T, REPLACE_FTRUNCATE. * lib/lseek.c (rpl_lseek) [_GL_WINDOWS_64_BIT_OFF_T]: Use _lseeki64 instead of lseek. * m4/lseek.m4 (gl_FUNC_LSEEK): Require gl_SYS_TYPES_H. Set REPLACE_LSEEK if WINDOWS_64_BIT_OFF_T is 1. * modules/lseek (Depends-on): Add sys_types. * lib/ftruncate.c: Put under GPLv3+. Include <windows.h>, msvc-nothrow.h. (SetFileSize): New function. (ftruncate) [_GL_WINDOWS_64_BIT_OFF_T]: New implementation. * m4/ftruncate.m4 (gl_FUNC_FTRUNCATE): Set REPLACE_FTRUNCATE on Windows if Large File Support is requested. * modules/ftruncate (configure.ac): Consider REPLACE_FTRUNCATE. (Depends-on): Add sys_types, msvc-nothrow. Update conditions. * lib/stdio.in.h: Add comments about off_t. * modules/stdio (Depends-on): Add sys_types. * lib/ftello.c [_GL_WINDOWS_64_BIT_OFF_T]: Use _ftelli64 or ftello64 instead of ftello. * m4/ftello.m4 (gl_FUNC_FTELLO): Require gl_SYS_TYPES_H. Set REPLACE_FTELLO if WINDOWS_64_BIT_OFF_T is 1. (gl_PREREQ_FTELLO): New macro. * modules/ftello (Depends-on): Add sys_types. (configure.ac): Incoke gl_PREREQ_FTELLO. * lib/fseeko.c [_GL_WINDOWS_64_BIT_OFF_T]: Use _fseeki64 or fseeko64 instead of fseeko. * m4/fseeko.m4 (gl_FUNC_FSEEKO): Require gl_SYS_TYPES_H. Set REPLACE_FSEEKO if WINDOWS_64_BIT_OFF_T is 1. (gl_PREREQ_FSEEKO): New macro. * modules/fseeko (Depends-on): Add sys_types. (configure.ac): Invoke gl_PREREQ_FSEEKO. * lib/sys_stat.in.h: Add comments about off_t. (stat, fstat) [WINDOWS_64_BIT_ST_SIZE]: Define to variants that use a 64-bit integer for st_size in 'struct stat'. * m4/sys_stat_h.m4 (gl_HEADER_SYS_STAT_H): Set WINDOWS_64_BIT_ST_SIZE. Define _GL_WINDOWS_64_BIT_ST_SIZE. * modules/sys_stat (Depends-on): Add sys_types. (Makefile.am): Substitute WINDOWS_64_BIT_ST_SIZE. * lib/stat.c (stat) [_GL_WINDOWS_64_BIT_ST_SIZE]: Define to _stati64 instead of stat or _stat. * lib/fstat.c [_GL_WINDOWS_64_BIT_ST_SIZE]: Use _fstati64 and 'struct _stati64' instead of fstat and 'struct stat'. * m4/fstat.m4 (gl_FUNC_FSTAT): Require gl_HEADER_SYS_STAT_H. Set REPLACE_FSTAT if WINDOWS_64_BIT_ST_SIZE is 1. Reported by Ray Satiro <raysatiro@yahoo.com>.
