Subject: [newlib-cygwin] Cygwin: simplify some function names
Date: Mon, 30 May 2022 15:06:45 +0000 (GMT)	[thread overview]
Message-ID: <20220530150645.4EDA03870870@sourceware.org> (raw)

https://sourceware.org/git/gitweb.cgi?p=newlib-cygwin.git;h=2d9b48760c48f19b2941f05ee6720f510700823c

commit 2d9b48760c48f19b2941f05ee6720f510700823c
Author: Ken Brown <kbrown@cornell.edu>
Date:   Sun May 22 15:18:48 2022 -0400

    Cygwin: simplify some function names
    
    Remove "32" or "64" from each of the following names: acl32,
    aclcheck32, aclfrommode32, aclfrompbits32, aclfromtext32, aclsort32,
    acltomode32, acltopbits32, acltotext32, facl32, fchown32, fcntl64,
    fstat64, _fstat64, _fstat64_r, ftruncate64, getgid32, getgrent32,
    getgrgid32, getgrnam32, getgroups32, getpwuid32, getpwuid_r32,
    getuid32, getuid32, initgroups32, lseek64, lstat64, mknod32, mmap64,
    setegid32, seteuid32, setgid32, setgroups32, setregid32, setreuid32,
    setuid32, stat64, _stat64_r, truncate64.
    
    Remove prototypes and macro definitions of these names.
    
    Remove "#ifndef __INSIDE_CYGWIN__" from some headers so that the new
    names will be available when compiling Cygwin.
    
    Remove aliases that are no longer needed.
    
    Include <unistd.h> in fhandler_clipboard.cc for the declarations of
    geteuid and getegid.
