[Mingw-cross-env-list] Re: zlib 1.2.5 fails on Ubuntu Linux (amd64) -- adler32.o: No such file or directory -> Solved

Hi Tony, 

There is no config.log produced for zlib, nor was there one for openssl from 
what I could tell...  I don't know why this is the case...

First, I applied the following to the zlib.mk, but the output is the same as 
the first 10 lines or so of the zlib.log I attached earlier.

Somehow $CC was not defined when it gets to here:

tmp-zlib/zlib-1.2.5/configure:254:  echo Building static library $STATICLIB 
version $VER with $CC.

Adding a CC define to the zlib.mk solved it!   Patch is attached.

Thanks for pointing me towards the configure script.
