Subject: AIX cpp bug: having macro arguments and character constants
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=07b6858f7b917ea2a8165266f68294a3b41bf5ce;p=p5sagit%2Fp5-mst-13.2.git

AIX cpp bug: having macro arguments and character constants
"the same" means trouble (here s and 's')
What broke now was 841 and 842 of t/op/pat.t, because of the
ANYOF_UNICODE_FOLD_SHARP_S() in utf8.h, ccversion 5.0.1.0
(note that breakage happened only under cc_r and usethreads+
useithreads)
