dirmngr: Require a c99 compiler
* configure.ac (USE_C99_CFLAGS): New ac_subst. Set to -std=gnu99 for
gcc.
* dirmngr/Makefile.am (AM_CFLAGS): Add USE_C99_CFLAGS.
(t_http_CFLAGS): Ditto.
(t_ldap_parse_uri_CFLAGS): Ditto.
(t_dns_stuff_CFLAGS): Ditto.
--
C99 and the GCC option is required for use with dns.c which makes
heavy use of C99 features. We should consider to switch GnuPG
entirely to C99 but enable gcc warnings to detect features which are
not supported by not-real-c99 compilers and which makes audits
harder (VLA etc.).
