Or use the workaround I had sent you. I recommend not mixing b19 and
b20.x compilers (unless you use egcs for both of course).

Yikes! Why are you using "ld" to link! You're missing the startup files,
and the program crashes and it has every right to. Also, why are you
linking with CRTDLL for a Cygwin app (if it's to get the wcscpy etc,
it's the wrong way to do it)! Never mix Cygwin and MS runtime DLLs.

I'm attaching my trivial patch for Jikes, so you can just type 'make'.
It also enables wide char versions of stuff from config.cpp when
__CYGWIN__ is defined.
