Thanks for trying this!

Could you please file issues in the Savannah bug tracker
(https://savannah.gnu.org/support/?func=additem&group=autoconf) for
this and any other problems you find? This will ensure that I don't
forget about them.

I think the line number in the syntax error must be wrong; there's no
"do :" anywhere in the snippet you quoted.  I'll poke at this some
later today, but can you tell me where to download a tarball of the
exact same version of Nasm that you are testing?  I want to be sure
I'm looking at the same thing.

Hm, I don't immediately see how we get from misbehavior in autoheader
with 'dnl' inside an AC_CHECK_THINGS([...]) list, to syntax errors in
configure.  Again, I'd like to poke at this some myself, can you tell
me where to get the exact version of flex that you are testing?
