See

Note especially the bit

  $ objdump -p hello.exe | grep "DLL Name"

to see which DLLs the binary is linked to.  You might also want to check
that you did "hash -r" under Cygwin bash and check that "type -a gcc" gets
you the Mingw gcc and not the Cygwin one.  What does your PATH variable
look like, i.e., how did you add Mingw's bin dir to the path?

Also make sure you don't have GCC_EXEC_PREFIX set and perhaps try removing
the Cygwin bin directory  (/usr/bin) from the path -- this isn't a long
term fix, but you might try it just to check which binary is being called.

HTH,
