Of course. I didn't find any such binary API problem in my tests.
I usually test perl for weeks until I release it.

But soon after I released it, we found out that some old XS modules did not=
 work
anymore and had to be recompiled.

I haven't yet found out why exactly. Debugging on cygwin is certainly
difficult compared to linux,
where I do have access to all stack params and symbols in shared libs,
and can reliably
set breakpoints in shared libs. Even if I use gdb-7 it does not work
most of the time.
