You can tell PHP_ADD_SOURCES to use special compile flags for
a specific compilation unit. These flags will preempt
anything php_config.h does.
dnl PHP_ADD_SOURCES(source-path, sources[, special-flags[, type]])
So, in your config.m4, you would determine these special
flags (either using a autoconf test or $host_alias), and call
PHP_ADD_SOURCES for the problematic source file. This is the
preferred way, because you can perform more elaborate checks
in config.m4 than using the C preprocessor.
