Re: CVS commit: pkgsrc/mk

This seems to have broken compilation on NetBSD 5.1:

root@pkgsrc-nb:/usr/pkgsrc/pkgtools/pkglint> make
make: "../../mk/compiler/../../mk/compiler/gcc.mk" line 257: Malformed
conditional (!empty(_NEED_GCC2:M[nN][oO]) &&
!empty(_NEED_GCC3:M[nN][oO]) &&  !empty(_NEED_GCC34:M[nN][oO]) &&
!empty(_NEED_GCC44:M[nN][oO]) &&  !empty(_NEED_GCC45:M[nN][oO]) &&
!empty(_NEED_GCC46:M[nN][oO]) &&  !empty(_NEED_GCC47:M[nN][oO]) &&
!empty(_NEED_GCC_AUX:M[nN][oO]))
make: Fatal errors encountered -- cannot continue

make: stopped in /usr/pkgsrc/pkgtools/pkglint
