   6 Phony compiler for testing SCons.

   8 Copies its source file to the target file, dropping lines that match
   9 a pattern, so we can recognize the tool has made a modification.
  10
  11 The first argument is the language (cc, c__, g77, etc.).
  12
  13 Recognizes a -x option to append the language to 'mygcc.out'
  14 for tracing purposes.

  16 Intended for use as $CC, $CXX, etc.
