[GRASS-dev] Error while compiling i.pr Windows GRASS6.4

[António Rocha]

Hi Glynn
I think you do magic because I've tried a couple of times without 
success and, right after I received your email I suceed compiling 
dllmain.c. :)

About OBJDIR, At GRASS.make it's defined as you said:
OBJDIR        = OBJ.$(ARCH)
So no problem with this

Now, with compiling i.pr:
I'm getting the following error (see below). it has something to do with 
drand48. drand48 is a function mentioned in line 42 of bootstrap.c of 
PRLIB folder.
Does this function ring a bell? I have searched and there is no file 
with that name in GRASS6 folder neither sourcecode or snapshot.

Thanks Glynn for your help
