- Log ----------------------------------------------------------------- commit fd998cbffc88a8e50fa34259c36a8db338168383 Author: Tony Cook <[email protected]> Date: Fri Jul 28 15:19:46 2017 +1000 make _GNU-ish function declarations visible on cygwin The lack of this caused several test failures on cygwin64, the one case I tracked down involved memmem() which is a GNU extension that cygwin supports. Since the compiler couldn't see the memmem() prototype it treated it's return value as int, which was then cast to (char *) preventing any type-mismatch warning, but since int is 32-bits and (char *) on cygwin64, the upper 32-bits of the pointer was cleared, resulting in a crash. After adding this a test cygwin64 build went from 30 or so test failures to one. ----------------------------------------------------------------------- Summary of changes: hints/cygwin.sh | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/hints/cygwin.sh b/hints/cygwin.sh index 21997dba74..20e0e58821 100644 --- a/hints/cygwin.sh +++ b/hints/cygwin.sh @@ -31,7 +31,7 @@ test -z "$optimize" && optimize='-O3' man3ext='3pm' test -z "$use64bitint" && use64bitint='define' test -z "$useithreads" && useithreads='define' -ccflags="$ccflags -DPERL_USE_SAFE_PUTENV -U__STRICT_ANSI__" +ccflags="$ccflags -DPERL_USE_SAFE_PUTENV -U__STRICT_ANSI__ -D_GNU_SOURCE" # - otherwise i686-cygwin archname='cygwin' -- Perl5 Master Repository
