Subject: replace exit() by throw sg_exception(). Of course, we have to be aware
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=2dfc0571356da7636cfd590fb386d34702b1ad7b;p=simgear.git

replace exit() by throw sg_exception(). Of course, we have to be aware
that interdependencies between sg libs are generally unwelcome, but
sg_exception is a rather basic part, and it's already used by xml, props,
scene, sound and, of course, structure. Since props and xml are core
libs, we can assume that sg_exceptions are available.  (OK'ed by Curt)
