Here is the example.  The problem is in the preprocessor.  This thing
compiles just fine with *my* traditional compiler, or with normal gcc.
It fails with gcc -traditional.

It has been observed in gcc 1.35 and 1.36.

#! /bin/sh
# This is a shell archive.  Remove anything before this line, then unpack
# it by saving it into a file and typing "sh file".  To overwrite existing
# files, type "sh file -c".  You can also feed this as standard input via
# unshar, or by typing "sh <file", e.g..  If this archive is complete, you
# will see the following message at the end:
#		"End of shell archive."
# Contents:  bug.c

if test -f 'bug.c' -a "${1}" != "-c" ; then 
  echo shar: Will not clobber existing file \"'bug.c'\"
else
echo shar: Extracting \"'bug.c'\" \(631 characters\)
sed "s/^X//" >'bug.c' <<'END_OF_FILE'
