[GRASS5] GRASS compilation on cygwin and IRIX

[Andreas Lange]

Hi,

i recompiled the latest CVS code on IRIX 6.5 with gcc 3.0 and on cygwin
(latest setup on W2K). 

On IRIX i have to manually set all include/library dirs or the libraries
are not found. libpng and libgd are not found, although specified with
--with-png-libs=/usr/freeware/lib32 \
--with-png-includes=/usr/freeware/include \

--with-gd-libs=/usr/freeware/lib32 \
--with-gd-includes=/usr/freeware/include \
libs are there (double checked that). 

If i put -lpng -lm to the header file, r.in.png and r.out.png compile. 
But the PNGdriver does not compile at all:

 
 SRC     = /disk2/opt/grass/grass/src
  CMD     = /disk2/opt/grass/grass/src/CMD
  UNUSED  = /disk2/opt/grass/grass/unused
  HEADER  = head.mips-sgi-irix6.5
  ARCH    = mips-sgi-irix6.5
  GISBASE = /disk2/opt/grass/grass/dist.mips-sgi-irix6.5
  VERSION = 5.0.0pre2 August 2001
