patches to the author.
+Notes on assembly language optimizations:
+
+ When using the old-style Makefiles, you can specify a configuration
+ that uses X86 assembly language optimizations (linux-3dnow for example).
+
+ The detection of MMX, 3DNow!, PIII/SSE, etc capability is done at
+ runtime. That means you can compile Mesa for 3DNow! optimizations
+ even if you don't have an AMD CPU.
+
+ However, your Linux binutils and assembler must understand the
+ special instructions in order to compile them. If you have
+ compilation problems, try upgrading your binutils.

Header and library files:
After you've compiled Mesa and tried the demos I recommend the following
procedure for "installing" Mesa.
