src.contrib problems...

[Michael Shapiro]

In info.grass.user you write:

ABS is a #define that was somehow missing from the code. YOu can
either figure out where it is used in the code and replace it
with abs() for integer, of fabs()( for floats. Or define it

#define ABS(x) ( (x) < 0 : -(x) : (x) )

Although for all but constants these kinds of #define contructs
are fraught with gotchas. Best use the abs() or fabs().
