4.1 on alpha

[Neel Smith]

I'm porting GRASS 4.1 to DEC alpha hardware using gcc for my compiler.
Has anyone else done this?

Specifically, at a first glance it looks like the functions G_window_overlap
and G_window_percentage_overlap are defined in src/libes/gis/wind_overlap.c
but are not declared extern anywhere -- a bunch of vector routines
that call them can't find them.  Should they be declared in gisdefs.h?

Thanks for any help -- gcc is a lot stricter than the old DEC compilers,
and before I wade through all the information it spits out, I'd like to
know if someone has already done it.
