This is a follow-up on my previous email where I had incorrectly configured mingw64 and cygwin.
I am still using cygwin's mintty+bash to invoke `sh make.sh "sbcl"'
Now the error is in phase 2 of the build (make-target-1.sh):
GNUmakefile:33: genesis/Makefile.features: No such file or directory
GNUmakefile:73: target 'TAGS' given more than once in the same rule
I found genesis.lisp and looked at it briefly. Assuming it builds the genesis/Makefile, I examined *FEATURES* in the 1.1.12 sbcl binary. I see :win32 and :x86-64 features.
I captured the build log, and I don't see the genesis.lisp being compiled.
