regex problems

[Sam Steingold]

when trying to upgrade to the latest gnulib regexp, I encountered the
following problems:

1. g++ cannot compile regexp:

./regex.h:569: error: expected primary-expression before "__restrict__"
./regex.h:569: error: expected `]' before "__restrict__"
./regex.h:569: error: expected `,' or `...' before "__restrict__"


2. autoconf does not recognize AC_CHECK_HEADERS_ONCE even though I put
   onceonly.m4 right next to the files that use it in my m4 directory:

configure:5675: error: possibly undefined macro: AC_CHECK_HEADERS_ONCE
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
configure:5676: error: possibly undefined macro: AC_CHECK_FUNCS_ONCE

thanks.
