So does MSVCRT.dll, which is what MinGW uses for its runtime.

^^^^^^^^^^^
Why are you linking in libc.a explicitly? The appropriate version should
be automatically linked in by the compiler.

What's LIBS set to? What's DLLNAME set to?

What's AS set to?

It also looks like you're using the Cygwin version of "ld", and dlltool
will probably invoke the Cygwin versions of tools, too. Try adding
-mno-cygwin to CC rather than CFLAGS, i.e.,
CC = gcc -mno-cygwin
CFLAGS = -O1 -fomit-frame-pointer -malign-double
...
and using $(CC) to link instead of $(LD) (you can pass flags to ld via
the -Wl,... options, IIRC).
