* Makefile.in (OBSOLETE_FUNCTIONS): Add open acl aclcheck aclfrommode aclfrompbits aclfromtext aclsort acltomode acltopbits acltotext chown facl fchown fgetpos fopen freopen fseeko fsetpos fstat ftello ftruncate getegid geteuid getgid getgrent getgrgid getgrnam getgroups getpwuid getpwuid_r getuid initgroups lchown lseek lstat mknod mmap seekdir setegid seteuid setgid setgroups setregid setreuid setuid stat telldir truncate. (NEW_FUNCTIONS): Add _open64 acl32 aclcheck32 aclfrommode32 aclfrompbits32 aclfromtext32 aclsort32 acltomode32 acltopbits32 acltotext32 chown32 facl32 fchown32 fgetpos64 fopen64 freopen64 fseeko64 fsetpos64 fstat64 ftello64 ftruncate64 getegid32 geteuid32 getgid32 getgrent32 getgrgid32 getgrnam32 getgroups32 getpwuid32 getpwuid_r32 getuid32 initgroups32 lchown32 lseek64 lstat64 mknod32 mmap64 seekdir64 setegid32 seteuid32 setgid32 setgroups32 setregid32 setreuid32 setuid32 stat64 telldir64 truncate64 to substitute the above. * cygserver_shm.h (class client_request_shm): Change uid_t and gid_t members to __uid32_t and __gid32_t. * cygwin.din: Add symbols acl32 aclcheck32 aclfrommode32 aclfrompbits32 aclfromtext32 aclsort32 acltomode32 acltopbits32 acltotext32 facl32 fgetpos64 fopen64 freopen64 fseeko64 fsetpos64 _fstat64 ftello64 _lseek64 mknod32 _open64. * glob.c: Include perprocess.h. (globtilde): Call getpwuid32 and getuid32 instead of getpwuid and getuid. (g_lstat): Check for applications API version to call the appropriate typed gl_lstat function. (g_stat): Ditto for gl_stat. * shm.cc (client_request_shm::client_request_shm): Call geteuid32 and getegid32 instead of geteuid and getegid throughout. * syscalls.cc (_open64): New alias for open. (_lseek64): New alias for lseek64. (_fstat64): New alias for fseek64. (mknod32): New function. (mknod): Calls mknod32 now. * winsup.h: Make function declarations for getuid32, geteuid32, and getpwuid32 accessible for plain C sources. Add declarations for getegid32 and getpwnam. * include/cygwin/version.h: Bum API minor number to 78. * include/sys/cygwin.h: Guard C++ specific members of struct per_process against inclusion in plain C sources. * include/sys/mman.h (mman): Add guard to avoid type clash when compiling Cygwin.
