Okay, makes sense to me. I'd like to proceed on the plan of getting
these rules (changelog & warning flags) into the xorg-macros.m4 before
anyone does a massive cleanup pass across all modules. It's not hard
to get a xorg-macros 1.2.0 release out quickly.
For the warnings one, I have a preference (not surprisingly) for the example
in the libxcb configure.ac that handles gcc & Sun Studio, though the gcc
warnings list there seems a bit short:
if test "x$GCC" = xyes ; then
CWARNFLAGS="-Wall -pedantic -Wpointer-arith \
-Wstrict-prototypes -Wmissing-declarations -Wnested-externs"
AC_CHECK_DECL([__SUNPRO_C], [SUNCC="yes"], [SUNCC="no"])
if test "x$SUNCC" = "xyes"; then
Certainly putting it in xorg-macros.m4 will make it easier to adjust for
new gcc warnings added in future releases and for additional compilers,
like the Intel compiler.
