svn commit: r1812263 - /httpd/httpd/trunk/configure.in

[rj...@apache.org]

New Revision: 1812263

URL: http://svn.apache.org/viewvc?rev=1812263&view=rev
Log:
Fix maintainer mode with GCC/Clang.

Setting -Wstrict-prototypes in combination
with -Werror leads to compiler errors during
configure checks (autoconf generates incomplete
prototypes).

Adding -Wno-error=strict-prototypes lets the
compiler tolerate those.

Possible future enhancement: remember such
"configure time only" flags and remove them
from CFLAGS before generating our build time
files (Makefile, config_vars.mk etc.), so that
the full -Werror is in place during building.
