Subject: | cc_inc_paths replaces INC provided on command line |
cc_inc_paths appears to replace INC rather than append to any INC
provided on the command line. This causes compilation to fail on
Strawberry Perl, for example, which sets INC (and LIB) as a Makefile.PL
option in CPAN.pm.
N.B. Problem detected on YAML::Syck. Symptom: make fails when run from
CPAN.pm, but succeeds when Makefile.PL and make run "by hand" in a
command shell without the default INC and LIB passed to Makefile.PL
