Or, you can use what I call "relative pathname fix" authored primarily
by Michael Meissner and Ian Taylor that allows you to freely move around
the tree and have it "just work". I know Jeff knows about all this,
and he knows the caveats, but I don't hear complaints from all the users
who use my win32 binary distribs of egcs.
The patch is slightly different for egcs-1.1.x and gcc-2.95, and both
versions are available in my patchsets.
for not-yet-released gcc-2.95:
After downloading the patchset, look for a file named *relative-path*
and that's the file you want.
It's unsupported, so please don't ask me how or if it works.
