Bug on gawk-3.1.1: grcat does nothing

[DervishD]

    Hello all :))

    In GNU awk 3.1.1, the grcat program doesn't cat the group
database because a wrong 'HAVE_' testing:

#ifndef HAVE_GETPGRENT
int main() { exit(0); }
#else

    The test should be for 'HAVE_GETGRENT', although it won't make
any difference: no test for 'getgrent()' is done on the configure
scripts.

    So, for fixing, test for 'getgrent()' and after that make the
conditional compilation directive check for 'HAVE_GETGRENT'.

    Thanks a lot for GNU awk, BTW ;))))
