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 Fixed by escaping two curly-braces with backslashes. Tested by getting past that point in the bootstrap successfully on hppa2.0w-hp-hpux11.00; formal test case not applicable.
