test case

The Windows version of WritePrivateProfileString reports an error if flushing
to file failed.

See attached test case. It tries to write to Z:\test.ini (which is expected to
fail as Z is mapped to /, with no write perms).

Under wine I get no output from the test, and the file isn't created. Failure
warnings do show up in +profile channel log:

trace:profile:PROFILE_Open path: L"Z:\test.ini"
warn:profile:PROFILE_Open profile file L"Z:\test.ini" not found
trace:profile:PROFILE_SetString (L"Section1",L"FirstKey",L"It all worked out
OK."):
trace:profile:PROFILE_SetString   creating key
warn:profile:PROFILE_FlushFile could not save profile file L"Z:\test.ini"
(error was 5)
warn:profile:PROFILE_FlushFile could not save profile file L"Z:\test.ini"
(error was 5)

Under Windows XP (where Z: drive doesn't exist), I get "failed with error 3"
message.
