Maybe dovecot's buildsystem should check for and use -std=c99? But then I wonder why it does build for RHEL5 and all recent Fedoras? I grepped the logs and found no explicit -std switch in any of the successful builds.

Wow, now I'm wondering too:

limits.h:102 # ifdef __USE_ISOC99 define LLONG_MAX, LLONG_MIN, ULLONG_MAX limits.h:111 # endif /* ISO C99 */ limits.h:131 #if defined __USE_ISOC99 && defined __GNUC__ ifndef LLONG_MIN, LLONG_MAX, ULLONG_MAX define theme limits.h:141 #endif

Dovecot used std=gnu99, when possible configure.in:300 # Use std=gnu99 if we have new enough gcc configure.in:301 old_cflags=$CFLAGS configure.in:302 CFLAGS="-std=gnu99"

gcc(1) gnu99 GNU dialect of ISO C99. When ISO C99 is fully implemented in GCC, this will become the default. …

Which gcc uses RHEL 6? It works for me with gcc-4.3 and gcc-4.4.

The gcc I used are

RHEL4 3.4.6 fails RHEL5 4.1.2 builds F11 4.4.1 builds F12 4.4.3 builds RHEL6 (beta1) 4.4.3 fails F13 4.4.4 builds
