- My recent change with -DUNICODE=1 required changing GetProfilesDirectory() to GetProfilesDirectoryA() for the ANSI version of the API. - enh's edit to my previous change deleted a test that used /proc/version, but I think another test was missed. Merge that test into another. Change-Id: Ic748549848e7be922bcbf218d5b0c3fca2a90704 Signed-off-by: Spencer Low <CompareAndSwap@gmail.com>
