Well, for a start, you'd need to link against the cygwin dll directly, and
it would need to be first on the linker command line.

Yes, that's how a cygwin executable should look; the first dependency should
be directly on the cygwin dll.

Hmm. It could also be a problem with the link stage. Make sure the
makefile is using 'gcc' to link the application and not trying to invoke 'ld'

I will do if I find myself some free time, but that's not really very likely
with my current workload....

No thank you. I can download them myself just as easily, and I should
follow the standard procedure described in the notes to try and reproduce the
One thing, though, by "*my* cygwin Makefile", do you mean the project
doesn't come with its own makefile and you had to put one together yourself?
Or is it just the one that the project came with or autogenerated using
configure or some similar script?
Anyway, check the linker invocation. Always use the gcc driver to invoke
the linker for you, never try and do it directly is the general rule.
Can't think of a witty .sigline today....
