svn commit: r1370928 - /subversion/trunk/subversion/libsvn_subr/sysinfo.c
Author: brane
Date: Wed Aug 8 20:08:20 2012
New Revision: 1370928
URL: http://svn.apache.org/viewvc?rev=1370928&view=rev
Log:
Rewrite the Windows release name constructor to use info from the registry
instead of using flaky mappings that rely on constants that may or may not
be defined in older SDK releases.
* subversion/libsvn_subr/sysinfo.c [WIN32]: Add comments.
(wcs_to_utf8, registry_value): New.
(win32_release_name): Rewrite.
(FNGETPRODUCTINFO, default_release_name): Remove.
