[mp3encoder] How to correctly compile lame with mingw

I've been trying to compile lame on mingw 3.2.0-rc3 and msys 1.0.11 on my win32 machine. I also added nasmw.exe to my C:\MinGW\bin and renamed it to nasm.exe. Anyway, here is the code I'be been using to get an athlon xp optimized build of lame: $ ./configure CFLAGS=-march=athlon-xp -Wall

[mp3encoder] still having problems compiling lame under mingw

1. Fresh tarball of lame source. 2. Edited /lame-3.96.1/libmp3/lame/mpglib_interface.c Changed #include interface.h to #include ../mpglib/interface.h 3. Same for /lame-3.96.1/mpglib/interface.c 4. $ ./configure --enable-nams CFLAGS=-march=athlon-xp -Wall -fstrength-reduce -finline-functions
