Jacques,

I don't know how much of the Gnu Compiler for Java shares with the Gnu C 
and C++ compilers, but why do you assume that availability of threading in 
"gcc" implies that Java threads will be available via "gcj?"


Moreover, why are you using "gcj" at all? Is there a reason the Sun J2SDK 
is unacceptable? It is far more mature and is eminently usable under 
Cygwin. I do a lot of Java work these days, so I'd be interested in hearing 
what is the appeal of gcj.


The following paragraph was included in Chris Faylor's the release 
announcement for gcc 3.2.1 (Subject: "[ANNOUNCEMENT] Updated/new: gcc 
3.2-1, gcc2-2.95.3-10, gcc-mingw-3.2-20020817-1"; Date: "Tue, 15 Oct 2002 
17:06:20 -0400 (EDT)"):

It seems that under Cygwin at least, "gcj" might not be ready for 
production use.
