GRASS 5.0 patches for Linux/Alpha (64-bit)

[Bill Hughes]

Hi *
  I have a patch for GRASS 5.0 on Linux/Alpha at:
http://grasshoppernet.com/~bhughes

  With this patch applied, GRASS 5.0 compiles and runs
on Alpha Linux, with minimal compiler warnings and no
segmentation violations.  (Yet.)

It's a substantial patch, but the size is mostly due
to the effects of running 'cproto' on the 'src/libes'
files to create ANSI prototypes.  This patch also adds
appropriate headers where malloc- signal- and str-
family functions are called.  All of this is to help
find those 'default int' calls that break so badly
in 64-bits.

There _are_ some actual code fixes in there, too.  None
of them are 64-bit specific - mostly they fix calls with
with the wrong number of arguments, or improper types.
