###############################################################################



#__ readme ____________________________________________________________________
#	nmake -f Makefile.MSVC
#		-> build lame and dll, but not mp3x
#		-> use Robert's code modifications
#		-> assume INTEL compiler available  
#		-> assume NASM available
#		-> assemble MMX code with NASM
#		-> optimize for PIII
#		-> single file optimizations
#		-> no compiler warnings
#
#	passing arguments, one can modify the default behaviour:
#	COMP=<not INTEL or BCC>    ->  use MS compiler
#	WARN=<anything but OFF>    ->  give verbose compiler warnings
#	ASM=<anything but YES>     ->  no NASM nor MMX
#	MMX=<anything but YES>     ->  do not assemble MMX code
#	CFG=<anything but RH>      ->  disable Robert's modifications
#	CPU=P1                     ->  optimize for Pentium instead of P II/III
#	CPU=P2                     ->  optimize for Pentium II/III, you need a PII or better
#	CPU=P3                     ->  optimize for Pentium III, you need a PIII or better
#	GTK=YES                    ->  have GTK, adds mp3x to default targets
#	PREC=SLOPPY                ->  use single float instead of double
#
#	Example:
#	nmake -f Makefile.MSVC CPU=P1 GTK=YES
