Tried to cross-build Octave for Windows with --enable-64, but got this when
builing libgcrypt:

:

Is this due to too aggressive optimization? "mov" looks like one of the most
basic CPU instructions to me....

My system: Mageia 2 32-bits (2 years old).

Not that it helps any, but it compiles fine on my Fedora 20 box .

According to the log, the -O2 optimization is used on mine.

A quick look on the internet shows a few other people have had similar
issues when building gcrrypt.
