It's sort of related to WINGISBASE; if you run the installation
in-place, WINGISBASE would be set to:

	c:\grasssrc\grass-6.3.0RC1\dist.i686-pc-mingw32

which would work. But WINGISBASE isn't set while building, only when
actually running GRASS.

It's more than just gis.m; C functions (e.g. fopen()) only understand
Windows syntax, not MinGW/MSys syntax. Forward slashes work in most
places (but not in the command interpreter), so either c:/grass63RC1
or c:\grass63RC1 will work, but /c/grass63RC1 won't.

g.dirseps will convert the separators, but not the /c/ -> c:/ for the
drive letter.

Does $(RUN_GISBASE) have the correct syntax?
