This has nothing to do with the problem, but might actually be a good point - 
maybe
you're right :-)

I had installed mysql_config and tried it out --

$mysql_config --cflags
-I/usr/include/mysql -g -pipe -Wp,-D_FORTIFY_SOURCE=2 -fexceptions 
-fstack-protector --param=ssp-buffer-size=4 -m32 -march=i386 -mtune=generic 
-fasynchronous-unwind-tables -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 
-D_LARGEFILE_SOURCE -fno-strict-aliasing -fwrapv

This seems to include both preprocessor and compiler flags, which is why I 
suggested
ADDITIONAL_CFLAGS and ADDITIONAL_OBJCFLAGS.  Feel free to suggest otherwise if 
you
know more about mysql_config or how to use it.

Thanks
