Hmm, looks like you've found a (non-cygwin specific) bug...

http://groups.google.com/groups?q=C_EFCN&ie=ISO-8859-1&hl=en&btnG=Google+Search

...not that it'll help much. FWIW the same fault crops up with gcc303
(compiled by me) and also fwiw "[gcc | gcc303] -c -gcoff -S tst.c"
followed by a subsequent "as -o tst.o tst.s" emits the same error ("as
-Z" won't force it). Both compilers use the same assembler - GNU
assembler version 2.12.90 (i686-pc-cygwin) using BFD version 2.12.90
20020706.

You'll notice it seems to be related/triggered by the forward reference.
This appears to be the only immediate work-around.
