Hi all,
I have been fiddling with GR3.1.2 on a PC running cygwin, for a couple
of weeks now and it works just fine. Upon the announcement of GR3.1.3 I
downloaded it and started to configure it and saw that SDL was not part
of my cygwin. Consequently, I downloaded SDL and built that and
reconfigured GR. However, after this I get a GR build error which I
don’t understand. ( This is like the say: if something works it hasn’t
enough features 
Any suggestions too why (the file select.h exist and is at
/usr/include/sys) looks like some environment variable is undefined but
to me it appears as if /usr/inclued is defined.
