Subject: Move all the compile time options that affect binary compatibility into
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=b75885fd5e21667265835a8400ce0c57b563c89e;p=p5sagit%2Fp5-mst-13.2.git

Move all the compile time options that affect binary compatibility into
a global variable PL_bincompat_options. Because the string will be
embedded in any shared perl library, it will allow a comparison check
to be added to perlmain.c in the future, to detect library mismatch.
