This is a suggestion of compilation directive to use when compiling PHP specifically for the audited code.
The selection made below is based on the extension usage, found in the code (--enable, --with) and also the absence of usage (--disable, --without).
Some local extensions (--pdo-mysql, --with-libmbfl...) are also mentionned for help.
