I remember this one, which was a hell of a job to find.

This was caused by a change to ecj1, which once used the syntax
-fzip-dependency=%U.zip and at some other time used the syntax 
-fzip-dependency %U.zip

Please find out which syntax the version of ecj1 that you are using
really wants, and we'll correct lang-specs.h accordingly.

Here's the diff:
