  Tested on HEAD with --enable-languages=c,c++ by running "make check-gcc
check-libstdc++ check-gcc-c++" (yes I know there's some redundant redundancy
in that list of targets) and then diff'ing the before-and-after outputs from
test_summary to make sure nothing changed (as well as eyeballing the summary
figures); nothing did.  Final patch attached (it hasn't changed any).  It's
a trivial patch, but I have an assign on file and in fact my employer
disclaimer is in the post as we speak.  (Finally got it signed just the
other day, hooray!)  No write privs; Zack, would you be so kind?  TIA!

	* gcc.c (default_compilers):  Clarify obscure error message when
  reading from standard input.


    cheers,
