Subject: Disable forking on Mac OS X. This should fix crashes on Snow Leopard.
X-Git-Tag: 2.0.0~5335
X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;h=42546d3f2c59f80abe43484fc93a111dbbfcc19e;p=features.git

Disable forking on Mac OS X. This should fix crashes on Snow Leopard.

It would be better to
* detect OS X version at run time (how??)
or
* use proper threads for autosave
