Compile with '-Wpedantic' in devel mode instead of '-pedantic'

Avoid 'Undefined symbol _mcount' with some Solaris compilers.

The '-pedantic' option is unknown to the comiler, but by coincidence
starts with a '-p' (gather performance data). When a file is compiled
with '-p' but is linked without '-p', 'Undefined symbol _mcount' occurs.
