[GRASS5] Re: [winGRASS] ARG_MAX and parser.c

[Andreas Lange]

Hi John, Markus, Glynn et al.

There is no ARG_MAX in src/libes/gis/parser.c and there will never be
one. 

I just added some ifdefs to
src.garden/grass.postgresql/d.site.pg/main.c, as this did not compile on
cygwin. 

On my cygwin install there is no ARG_MAX defined anywhere, only
_POSIX_ARG_MAX (in limits.h). So i defined ARG_MAX to be _POSIX_ARG_MAX
if it is undefined. This should be 4096 in any case.  

What i changed may not be very sophisticated, but i think the
grass.postgresql code needs some major cleanup. It compiles now on Linux
and cygwin and if someone experiences any problems, i'll change that to
something that works on all platforms.

Hope that is clarified now, 

cu
