You have a too new version of gcc, where the -mno-cygwin flag is no longer
supported. Installing the Cygwin package mingw-gcc-core should work, but it
requires some makefile changes as well.

I tried updating the rbspeex makefile, but it didn't work as expected. I changed
the Cygwin check in tools/rbspeex/Makefile to this:

ifeq ($(findstring CYGWIN,$(shell uname)),CYGWIN)
ifeq ($(shell which i686-pc-mingw32-gcc),/usr/bin/i686-pc-mingw32-gcc)
CC := /usr/bin/i686-pc-mingw32-gcc
else
CFLAGS+=-mno-cygwin
endif
endif

But that didn't have the expected effect. It did compile, but it didn't use the
CC I had specified, but rather "/usr/bin/gcc" (not building a standalone
executable). The "ifeq" seems correct, because I can set CROSS there, and have
it used as expected (this doesn't help though, CC being set as it is...).

Perhaps someone more familiar with GNU make can help (both getting the CC change
to work, and detect mingw-gcc in a better way)?
