Subject: The PERL_EFF_ACCESS_[RWX]_OK macros are all defined as triples, so
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=d7558cadd708841cd632b5ecc8f461233367b84d;p=p5sagit%2Fp5-mst-13.2.git

The PERL_EFF_ACCESS_[RWX]_OK macros are all defined as triples, so
can be refactored to a single platform dependent PERL_EFF_ACCESS macro
with the other 3 implemented in terms of it.
