It seems that there is a variable FONTCONFIG_FILE, but it doesn't quite work 
on Windows, at least in version 2.2.3. If you look in run-test.sh, you will 
see that they set the variable there.

I configured fontconfig and did not specify confdir. fc-list worked. I then 
set FONTCONFIG_FILE to foo, and fc-list could not load the default config 
file. I then set FONTCONFIG_FILE to c:\mingw\etc\fonts\fonts.conf, and it 
still couldn't find the config file, which was not expected. I deleted the 
FONTCONFIG_FILE variable, and it started working again.

There is also FONTCONFIG_PATH, which I believe is the list of directories 
where it should look for fonts, but I am not sure.

I eventually determined that you have to enter the conf file name  without 
the drive letter, i.e. \mingw\etc\fonts\fonts.conf. It is probably treating 
the ':' as a path separator.

That is exactly what it does in DllMain.

If it has not been fixed, then look at src/fccfg.c at FcConfigFilename and 
optionally FcConfigGetPath. I think the easiest thing for *you* would be to 
fix the part where it reads %FONTCONFIG_FILE%, then tell your users to set 
FONTCONFIG_FILE. Of course, it is possible that your users don't mind the 
additional step, or would even prefer to not to keep confdir in ./mplayer.
