No problem, just wanted to make that comment for the record, R2465 works
perfectly fine for now.

OK.

Wrong hypothesis then (-: Do you agree however that we can change
infrastructure/mingw/configure.sh to include
"--enable-static-bin" to eliminate the dependency on mgwz.dll? Do you need
any other information for this change request?

Sorry for being imprecise: the UPX step was rather intended to give other
people on this list an interesting idea that I only stumbled upon by
chance, not as part of the official build process. Stripping is also a good
suggestion. 

Would it perhaps be possible to have stripping included in the Makefile,
perhaps by introducing the targets make-release and make-debug, with the
default make pointing to make-debug, and make-release doing the stripping
of resulting binaries automatically after linking?
