Ok, tried again... without much luck. I added the spec file folder,
and it complains it does not find jc1.exe. Ok, I added the folder
holding jc1.exe as well and... nothing happens! I mean no error 
messages, but no output as well. This is the output of my gcj 
invocation, run in verbose mode:

Doh... I also checked in the temp folder where jc1 is supposed to
generate the output file, there's nothing...
I have the impression of being Don Chichotte battling
agains the windmills...
Is there any way to get the full configuration parameters gcj is using
when linking to the standard libraries?
