- Added library detection to configure.in, to detect

SVGAlib, X, GL, SDL, and GLIDE.  Modified the
  Makefile.am's to match the new configure variables.
  Now people don't have to manually hack src/Makefile.am to
  build their targets.
- Fixed a typo in src/qgl.h with the #define
- Added new automake generated files to bootstrap's clean
  command.
- Added build requirements to HACKING, as we now need
  automake 1.6.
- Removed note in README about the asm FPE bug, as I seem to
  have inadvertently fixed this without meaning to.

 HACKING on quake2
 =================
 
+To build quake2 from CVS, you will need the following software:
+ - automake, 1.6
+ - autoconf, 2.50 or higher
+ - GNU make
+
 Note to developers: bsd/, irix/ and solaris/ are NO LONGER PERTINENT!
 
 linux/ was renamed src/, so hack in there.  As we port to more arch/os's,

 If you are checking this out from CVS, run the bootstrap command first to set
