Re: Patch to pass -pedantic flag to cpplib

[Dave Brolley <brolley at cygnus dot com>]

I don't think that your patch will work with some languages (fortran?) that don't
link to libcpp.a, even when USE_CPPLIB is configured. cpplib inbterfaces can't be
used directly from toplev.c. I suggest the attached patch which uses the same
indirection as the language specific options (namely lang_decode_option) to pass
-pedantic to cpplib.
