Hello grassusers 
I am trying to compile grass5.0beta5 as a "user" at ONYX server(8 CPU)
under IRIX6.5. and I got following error message:
 
In file includedfrom /usr/include/rpc/types.h:67,
                 from G.h:3,
                 from put_row.c:115:
/usr/gnu/lib/gcc-lib/mips-sgi-irix6-o32/2.8.1/include/stdlib.h:207:
conflicting types for `initstate' /usr/include/math.h:731: previous
declaration of `initstate' *** Error code 1 (bu21) GISGEN failure at STEP:
src/libes/gis *** Error code 1 (bu21 

on this message compilation has crashed. Since it is a very nice machine I
would appreciate any hints to make compilation succesful. 
Thanks,
