I'm building CppUTest from http://cpputest.sf.net with cygwin.

make from the CppUTest path results in a huge list of errors with
___cxa_atexit reference, for e.g.:

tests/CommandLineArgumentsTest.o: In function
`__static_initialization_and_destruction_0':
/cygdrive/d/work/chord/CppUTest/tests/CommandLineArgumentsTest.cpp:72:
undefined reference to `___dso_handle'
/cygdrive/d/work/chord/CppUTest/tests/CommandLineArgumentsTest.cpp:72:
undefined reference to `___cxa_atexit'

I believe it has something to do with cygwin's latest gcc's being
compiled with "--disable-__cxa_atexit". Would it work on cygwin if I
compile gcc with --enable-__cxa_atexit option? Any other options?
