Small bug in cccp: the preprocessor exits with a fatal error when
given no output file argument (as when invoked by gcc -E or gcc -M).
Version: gcc version 1.30
Test input: any file at all (gcc's version.c is sufficient).
Test invocation:
nex% gcc -v -E version.c
gcc version 1.30
/usr/local/lib/gcc-cpp -v -undef -D__GNU__ -D__GNUC__ -Dvax -Dunix version.c
GNU CPP version 1.30
cpp: Is a directory for `'
