hi folks,
I'm trying to build a toolchain in cygwin for uclinux.
The program "elf2flt" links against both libcygwin and libiberty from
arm-uclinux-elf-binutils.
There are "getopt" implementations in both libs and I got the error message:

It seems libcygwin is linked prior to libiberty but it does not work.
How can I link the correct lib?
Any help is appreciated!
