Hi Ken,

this reminds me of Taco's attempts some time ago to cross-build on linux for
mingw32, with similar failures.  The reason was 'tangle' (not
'tangle$(EXEEXT)') as a dependency that caused Make to apply a builtin rule. 
Lacking the required '-Ixxx' directives and libraries that rule clearly
failed (as in your case).

Could be, there is still such a dependency lurking around, although I had
thought they were now all corrected.

Can you try to 'touch tangle' in the texk/web2c build directory and then run
'make', first in the texk/web2c build directory and if that succeeds in the
top-level build directory.  This should then continue the build process and
possibly uncover more problems of the same kind.

Regards
Peter
