For compile-time fortify checks (such as the wrappers for type-safe

I do not want to add Dejagnu as a dependency to the glibc test suite,
but I wonder if you could share any lessons learned from the testing
support facility in GCC.
Would you suggest to mirror the GCC directives exactly?
I probably have to implement the testing directive parser as a small C
Writing a parser in C or C++ or other high level language wouldn't
be my first (or second) choice. If all I needed to do is check for
compiler errors and warnings on the source lines they point to, my
first choice would be a POSIX shell script combined with grep, sed,
