Subject: Be more careful when using xlocale
X-Git-Tag: 2.33.8~51
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4c255d4602b4c6f65031588ff30342c36e250567;p=platform%2Fupstream%2Fglib.git

Be more careful when using xlocale

Bug 680074 shows that we may end up in situations where only
some of the xlocale functions we need are available. Rather than
trying to find the minimal set of required functions for each
use, define a global USE_XLOCALE and only use any xlocale functions
if we have a full set.
