Hi,
I have a module that assumes that the compiler provides the erfl() function.
The assumption is obviously wrong.
What's the best way of determining, during the 'perl Makefile.PL' stage of the build, whether the compiler does, in fact, provide the erfl() function ?

The cpan-tester FAIL reports that I'm receiving en-masse wrt BSD systems all seem to relate to gcc compilers. (I don't think there's a FAIL report there for anything other than BSD && gcc.)
Therefore, I'm quite happy (for the moment, anyway) to limit this question/discussion to gcc compilers only.

Cheers,
Rob
