Heimdal vs FORTIFY_SOURCE

[Buchan Milne <bgmilne@mandriva.org>]

As I referred to in another mail, my packages build fine on all recent 
versions of Mandriva, and RHEL4, but not on RHEL5.

Compilation fails as follows:
if 
gcc  -DHAVE_CONFIG_H -I. -I. -I../../include  -I../../lib/roken -I../../lib/roken -DBUILD_ROKEN_LIB -I/usr/include/et  -D_FILE_OFFSET_BITS=64 -DTEST_SNPRINTF -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m32 -march=i386 -mtune=generic -fasynchronous-unwind-tables -fno-omit-frame-pointer -MT

        then 
mv -f ".deps/snprintf_test-snprintf-test.Tpo" ".deps/snprintf_test-snprintf-test.Po"; 
else rm -f ".deps/snprintf_test-snprintf-test.Tpo"; exit 1; fi

If I remove "-Wp,-D_FORTIFY_SOURCE=2" from CFLAGS, it builds ... any hints as 
to a better fix?
