Hi all,
I seems that GCC fails to compile the code generated by the AC_C_CONST
macro if the -O2 -Wall -Werror CFLAGS are specified.
I tried with both autoconf 2.61 and 2.62.17-684d2-dirty (taken from git
repo). GCC version is 4.1.2.
Below is the part of the config.log file describing what
Hi all,
I encountered a problem with the AC_C_CONST macro when using -O2 -Wall
-Werror as CFLAGS. The AC_C_CONST macro broke with similar CFLAGS some
time ago [1]. Thus I created a patch that extends the AT_CHECK_MACRO
macro used in the testsuite.

Thanks for the patch. However, I don't want to apply it just yet.
There is a bigger issue that several tests fail when running the
autoconf testsuite under -Wall -Werror (I have tried this in the
past); in particular, some warnings occur when testing for functions
that might be implemented
Thanks for the report. AC_C_CONST is obsolete - as of autoconf 2.60,
there were no known compilers on typical porting platforms that lacked
const support. The easier fix is just to delete that macro from gcc's
configure.ac, and require C89 support from the system compiler.

gcc isn't the only compiler, but -fno-builtin is not universally
available. Blindly setting CFLAGS to include options that are not
It seems that AC_OPENMP always defaults to enabled by default. This
causes problems for packages that would prefer that this feature be
disabled by default. OpenMP is pretty invasive since it adds
additional library dependencies.
Is there a way to use AC_OPENMP in a default disabled state
Hello again,
I have been reading the Autoconf documentation regarding site specific
configuration files.
I have been trying to find a way to change sysconfdir to just be
${sysconfdir}, not ${prefix}/${sysconfdir}. I'd like to set that as a
configure default for my program.
I see that this is
