Build Process Question

In the build for a PHP module I'm developing I need to add -D_FILE_OFFSET_BITS=64 to $CFLAGS to get my module to compile. When I add it in config.m4: CFLAGS="$CFLAGS -D_FILE_OFFSET_BITS=64" it is added to the $CFLAGS for the whole PHP build process and seems to cause warnings in other modules. Is there a way to add it just to my piece of the build? Same with header files, is there a way to add an include path during my module's part of the build and then remove it when the module is done? I am new to linux/php development and any enlightenment would be appreciated.
