Hello,
I recently came across a false negative in GCC's detection of array bounds
violation. At first, I thought the other tool (PC-Lint) was having false
positive, but it turns out to be correct. The false negative occurs in GCC
4.3, 4.4.1, and latest trunk (4.5). I'm curious to understand ho

Next, a stack of libiberty files were not compiled - strcasecmp,
vasprintf, asprintf, getpagesize, strdup. I don't know why this
would be the case, because e.g. HAVE_STRCASECMP is
not defined. Anyway, I added them to the source list manually,
and with a script, awk and m4, I was able to produce

Ok, now I have some results from the auto-compile-script-generation.
I got it to work, but it required some manual corrections.
First of all, I got link errors, because sched-ebb etc were trying
to call various functions, but those functions were not being
compiled in because INSN_SCHEDULING was
