>Description:
when compiling a file only including <unistd.h> and
<GL/glx.h>, a warning about 'read' is produced.

In file included from c.c:2:
/usr/X11R6/include/GL/glx.h:303: warning: declaration of `read' shadows global declaration
/usr/X11R6/include/G
>How-To-Repeat:
gcc -I/usr/X11R6/include -Wshadow -c c.c
where c.c is:
#include <unistd.h>
#include <GL/glx.h>
>Fix:
change glx.h, line 303, prototype for glXMakeContextCurrent
to use a name other than read as a parameter.
Perhaps use "GLXDrawable reed"
