[GRASSLIST:4005] Re: problem compiling new 5.7 source...solved and thrilled

I found the apparent problem in the nviz compilation. I had to change 
the include line
#include <GL/glx.h>
to
#include "/usr/local/mesa/include/glx.h"

and all proceeds to the end. The new interface is beautiful. I ca't wait 
to see what's new.
Thank you again,

Summary /fixes (in case it's useful)

Linux slackware 9.1 kv 2.4.20 ,  gcc 3.2.2, x86 PIII

some of the include statements in nad2bin , g.proj and nviz didn't 
reflect the parameters in my configure command

lib/proj/nad2bin.c   required a change from #include <projects.h>
general/gproj/main.c   deleted the #include <cpl_csv.h>
visualization/nviz/src/dozoom.c   required a change from #include 
<GL/glx.h> to #include "/usr/local/mesa/include/glx.h"
