What about various #ifdefs or bumping up the requirements?

Also, I could not get qemu-fast working with any glibc >=2.3.1 compiled 
from pristine sources according to instructions from Linux From Scratch.

Qemu-fast compiles, but doesn't work with glibc >=2.3.1. It does not 
compile at all with glibc-2.3.3-cvs with TLS enabled. See my message 
"qemu and modern glibc" for changes to qemu that make qemu-fast at least 
compile on glibc >=2.3.3-cvs. Please confirm privately that you have 
read this message.

The tail of qemu.log is:

----------------
IN:
0x000c625d:  repz stos %ax,%es:(%di)

----------------
IN:
0x000c625d:  repz stos %ax,%es:(%di)

(repeated infinitely without any OUT, even if I add out_asm to the -d 
switch). Plain non-fast qemu works perfectly.

What are known good _pristine_ (not RedHat) glibc versions that are 
capable of producing a good qemu-fast binary?

On what distribution does the qemu development happen? What are 
binutils/gcc/glibc versions?
