I don't. I accept the fact that there is no home directory, and look
for / store personal config files in the gimp installation directory
suffixed with the user name (which can be "somebody" if the user name
isn't known). For instance, C:\gimp\gimprc.somebody. Hmm, probably one
should be able to ovberride this in the system gimprc in case the
installation directory is read-only.

On Windows, I get the installation directory by asking the system for
the executable name using GetModuleFileName. On Unix, one would have
to search the PATH for argv[0]. Then you don't have to know the
installation directory when compiling (DATADIR).

Well, not in not g_get_home_dir (), but sure, parts of gimprc.c
could/should be made more generic and moved into glib. Functions to
find out the installation directory (from argv[0] and PAT, or from the
system), to handle building the names of various personal
configuration files, to rename a pesonal config file to .old and open
a new, etc.
