Yes, it should.  If it doesn't work for you, please post the smallest 
code fragment that fails and please explain how does it fail.

In general, you just include an assembly instruction as a quoted string 
argument to a pseudo-function asm().  You don't have to search on the net 
for the docs of how to do it: the GCC documentation explains this 
facility in great detail.  Just get the GCC docs archive (gcc263dc.zip) 
and read there under the ``Extensions'' chapter.  If you insist on 
reading this through the net, point your Web browser to this URL:

If you are used to inline programming in assembly for the PC, then check
out the DJGPP FAQ list (available as faq102.zip from the same place you
get DJGPP).  It discusses in section 17.1 the differences between AT&T
assembly syntax and Intel assembly syntax and points you to further docs
on this point.
