Makefile.ag
Log Message:
since compilation with strict compiler settings have (once again)
proved to be bery useful to locate bugs in the code,
we nolonger simply disable all of the strict "X_CFLAGS"
in directories that (also) contain swig-code,
but rather selectively disable only those extra warnings/errors
that do indeed occur in code that is beyond our control.
(This affects only compilation with --enable-strict.)
