Subject: Define _XOPEN_SOURCE=500 on HP-UX
X-Git-Tag: v3.0.4~2^2~192
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1914cf5d06cac2e304b73cd1ff223ba1edd7c464;p=thirdparty%2Flibarchive.git

Define _XOPEN_SOURCE=500 on HP-UX

The HP-UX <wchar.h> header provides 'mbstate_t' in C89/C90 mode only if
_XOPEN_SOURCE is defined to exactly 500.  Type 'mbstate_t' was
introduced in C89/C90 Normative Amendment 1, aka C94/C95, adding support
international character sets.  It is part of C99 but not C89/C90.
