[snip] //-style comments are part of C99, and are enabled by default. gcc 2.95.3 disables //-style comments if -ansi is used[0], and I assume gcc 2.96 does the same (but I don't know where to find docs for 2.96, because it was a redhat special and not an official gnu release. ) I don't see a flag to specifically enable or disable them.
