Add a test.taintwarn makefile target,

[perl5.git] / win32 / buildext.pl

=head1 NAME

buildext.pl - build extensions

=head1 SYNOPSIS

    buildext.pl make [-make_opts] dep directory [target] !ext1 !ext2

E.g.

    buildext.pl nmake -nologo perldll.def ..\ext

    buildext.pl nmake -nologo perldll.def ..\ext clean

    buildext.pl dmake perldll.def ..\ext

    buildext.pl dmake perldll.def ..\ext clean

Will skip building extensions which are marked with an '!' char.
Mostly because they still not ported to specified platform.
