Last night I hacked the lame makefile for DJGPP.
It's attached to this email
I have tested it with DJGPP 2.03, GCC 2.95 (19990728 release),
the DJGPP port of GNU make 3.78.1 and lame 3.85 beta.
Here are some timings for my Celeron 400 Mhz.
Test track: We Care A Lot by Faith No More - Track 01 - Greatest Hits,
encoded with the -h switch.
1:28 - MSVC 6.0 with default project file
1:47 - DJGPP with default compiler options
1:40 - DJGPP with second set of options
1:40 - DJGPP with third set of options (the ones for GCC 2.95.2)
1:41 - gcc under linux on the same machine with the 3rd set
of compiler options
1.37 - mingw32, gcc 2.95.2 for win32 (3rd set of compiler options)
see: http://www.xraylith.wisc.edu/~khan/software/gnu-win32/
So on my system at least, DJGPP isn't quite as fast as MSVC 6.
However it's still pretty good and freely available.
Mingw32 is slightly faster and produces true win32 executables which
should be better for windows NT users. (AFAIK DJGPP only can't use long
filenames under win NT.)
mingw32 has a problem with this in brhist.c:
#ifdef _WIN32
COORD Pos;
HANDLE CH;
CONSOLE_SCREEN_BUFFER_INFO CSBI;
#endif
because COORD isn't in the mingw32 include files.

# Makefile for LAME 3.xx using DJGPP (DJ Delorie's DOS port of GCC)
# based on the original lame makefile
#
# Hints:
#
# To compile, use: make -f Makefile.djgpp
#
# Make sure that you have the DJGPP make utility installed (get it from where you got
DJGPP)
#
# Use UPX to compress the exe to less half the original size.
#
## Some of the changes (things that don't work with DOS/DJGPP)
## removed VBR histogram capability
## removed references to GTK
## removed references to rtp
## make clean is a hack because the dos prompt doesn't like really long command lines
## removed -pipe from CC_OPTS
# generic defaults. OS specific options go in versious sections below
