This patch addresses a build failure on HP-UX due to the vendor awk(1) apparently treating a lone curly-brace as an incomplete repetition operator: [...] awk -f /home/src/gcc-4.7.2/gcc/opt-functions.awk -f /home/src/gcc-4.7.2/gcc/opt-read.awk \ -f /home/src/gcc-4.7.2/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 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. ChangeLog entry: PR bootstrap/53607 * opt-functions.awk: Fix compatibility with HP-UX awk.
