Subject: Expand ~~/ to bundle path (OSX)
X-Git-Url: http://winboard.nl/cgi-bin?p=xboard.git;a=commitdiff_plain;h=686059ae9cb5a33576ae0e91ddf88b14c90c9218

Expand ~~/ to bundle path (OSX)

DATADIR is #defined in WinBoard as "~~" to make the expansion a no-op
there. Same for Linux compiles. For OS X it is #defined as a variable,
obtained from GTK-OSX at startup.
