This is such a basic problem I must be doing something daft. I have a

external references seem to be getting resolved. This is on Win7 and I
have MinGW and msys installed using the msys make.
The GNU linker used on MinGW is a Unix linker, and as such the order
of the -l options is significant and for each -l option it only pulls
in the objects required at that point in the link. This is different
from how Windows linkers behave. You most likely need to repeat your
-l options or use the --start-group/--end-group linker options.

I had read that and I was quite careful to ensure the correct order. I
did a test with just two libraries where the second referenced the first
and as in my follow-up message it didn't pull them in unless I made a
call into each from my main code. It's like the symbol tables are messed
up somehow.
I would check the instructions for creating DLLs... I myself haven't
done that "manually" for years but I remember that being something
weird, not like creating usual Win32 executables. Creating Win32s
executables maybe could be compared to creating DLLs, that was a 2-phase
process because of those required "relocations", the functions
needed being relocatable in the address space, not "linear"...
