Hi folks,

First of all I'd like to thank Giovanni P. Deretta for the brilliant
idea and implementation of courotines [1].  Unfortunately, coroutines
haven't been reviewed and included into the official boost repository
yet but I believe it's just a matter of time.

I downloaded the latest version "boost-coroutine-2009-04-30.tar.gz"
from the boost vault[2] and it seems to build/run just fine on linux
x86.
However trying to build it on x86_64 gave me a compile time error -
"This file is for x86 CPUs only" in swapcontext.cpp, since there is a
#if !defined(i386) guard which produces this error.

I was naive and tried to change "#if !defined(i386)" to "if
!defined(i386) && !defined(__x86_64__)" in hope it would "just work"
for x86_64...well, it didn't ;)

I'm not that good in assembler(I have only basic knowledge), maybe
someone stumbled upon the same problem and has a working patch for
x86_64? Or maybe someone can give some pointers on how to make
couroutines x86_64 compatible? IMHO, it shouldn't be very hard and I
can try to do it myself, I just don't know where to start :)

Thanks a lot in advance.
