Re: [Nel] Building NeL from CVS

[David Castro]

Aha.  I was able to patch the driver_opengl.h file.  It appears that 
somehow the declaration of the H_AUTO_OGL define was only located in the 
ifdef for NL_OS_WINDOWS, so I duplicated it for the else block 
(NL_OS_UNIX) also.  Compiled and installed just fine.  I have attached a 
patch for this file.

Cheers,
David
