Subject: Using RegQueryValueEx instead of RegGetValue
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;ds=sidebyside;h=43601f654675c8734c9ca5850cc41dac16d1989a;p=ext%2Fsubsurface.git

Using RegQueryValueEx instead of RegGetValue

Provides compatibility with winxp-32bit in gtk-gui.c,
since RegGetValue is only available on the 64bit build of the OS.

Fixed whitespace issues, fixed obvious typo (this patch clearly wasn't
even compile tested)
