Ok, you're right, adding MXE_CCAS doesn't fix the problem.

Your patch 'msvc-nettle-1.patch' introduce a variable CCAS to
'config.make.in'. In 'nettle.mk' you set CCAS=gcc for msvc builds. For
non-msvc builds (or at least at my system) CCAS is unknown, so compiling
will fail.

The real problem is that the mentioned patch should *not* be applied on non-MSVC system. Actually, I see that I made a mistake there [1]. This should use "$(MXE_SYSTEM)" instead of hardcoded "msvc". That's why the patch gets applied.

Should be fixed with this:
