>Description:
        When building devel/autoconf on FreeBSD (6.2 and 7) system's m4 is
        called despite GNU m4 is required and found:

        checking for expr... /usr/pkgsrc/devel/autoconf/work/.tools/bin/expr
        checking for gm4... /usr/pkg/bin/gm4
        checking whether m4 supports frozen files... no
        configure: error: GNU M4 1.4 is required
>How-To-Repeat:
        Bootstrap pkgsrc on FreeBSD and install devel/autoconf
>Fix:
