No more than the rest of us. :)

That is not portable at all.  AIX 4 has no /proc, and older unixes may
have /proc, but not the maps stuff.  Unless Posix has an API for doing
this (I don't believe it does), it's not a viable solution.

Really, the only issue here is having a way for GTK to find the loadable
modules and plugins and things.  The linker can find the libraries based
on LD_LIBRARY_PATH, and GTK, Pango, and others can (hopefully) be set to
check environment variables to find their modules and data files.
That's the most portable way to do this, the cleanest, and least
dependent on OS-specific behavior.
