Proposed fix

Bootstrapping 4.7.0 on an HP-UX 11.00 system fails with

[...]
echo timestamp > s-options
awk -f /home/src/gcc-4.7.0/gcc/opt-functions.awk -f /tg/freepor
t/src/gcc/gcc--4.7.0-tera/gcc/opt-read.awk \
               -f /home/src/gcc-4.7.0/gcc/opth-gen.awk \
               < optionlist > tmp-options.h
awk: There is a regular expression error.
        ?, *, or + not preceded by valid regular expression
 The source line number is 90.
 The error context is
                        if (flags ~ >>>  "^{") <<< 
gmake[3]: *** [s-options-h] Error 2
gmake[3]: Leaving directory `/tmp/gcc-build/gcc'
gmake[2]: *** [all-stage1-gcc] Error 2
gmake[2]: Leaving directory `/tmp/gcc-build'
gmake[1]: *** [stage1-bubble] Error 2
gmake[1]: Leaving directory `/tmp/gcc-build'
gmake: *** [bootstrap-lean] Error 2


The fix for this is fairly trivial; patch against SVN is attached.

--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So this was fixed in GCC 7 by r7-5331 (aka PR 78766) so I am going to close
this as a dup of bug 78766.
