hi,

ok, this is the first time i'm writing here, because i think that i won't
have anything intelligent to tell you. i'm amazed.

for the records: the takehiro-version does not run when compiled with pgcc
2.95.1. it gives me a "memory allocation error". processor is a K6, it
does not matter which compiler options i turn off. 

btw: it seems like in pgcc 2.95.1 -ffast-math is broken. using it when
compiling the standard lame 2.25 gives me a (nearly) constant result of 32
kbit/s with options -V0 -d -h. the result is of course awful.

should we write this into the makefile?

ciao,

olaf
