Without any gengtype.c changes, I wonder if just following change wouldn't
do it, gengtype considers only char and unsigned char pointers as strings
with the special strlen handling, all other scalar types are treated
differently it seems, and signed char aliases everything too.
Or s/signed char/void/ in the patch is perhaps even better.
I've bootstrapped/regtested this on x86_64-linux and i686-linux,
and hopefully verified the problem from the PR is gone, by running over
610 successful PCH write + PCH read cycles as described in
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=59436#c14 , no failures
with the patch, while on a tree from yesterday without the patch I could
reproduce it 17 times, on average every 22 iterations (from 2 to 81).
Ok for trunk (and after a while for 4.8)?
