Compiling any Fortran file with -fmudflap results in an ICE:
f951: warning: command line option "-fno-builtin" is valid for
C/C++/ObjC/ObjC++ but not for Fortran
lall.f:0: internal compiler error: mudflap: this language is not supported
Please submit a full bug report, [etc.]
In addition the warning is bogus as "-fno-builtin" wasn't specified.
This happens since 4.0.0.
