[PATCH] fall back on USERPROFILE variable if HOME is unset

[Diego Biurrun]

Hi,

this is a small patch we have lying around in the MPlayer tree.  It came
with the following commit log message and should be safe to apply:

  fallback to USERPROFILE environment variable for caching CSS keys
  when HOME is not set (for MinGW builds running outside of MinGW).
