I finally figured out what is going wrong.
But first let me say what a PITA it is to debug configure. It is utterly,
completely painful! When you insert random "exit"s, like you usually do
with scripts that are too garbled and complex and ugly to understand (the
worst Perl code I ever saw was not as ugly), it does not exit _at all_!
Turns out that the compilation fails:
...\ld.exe: cannot find -lsocket 1 exit status
Nice.
FWIW it tries to link with
cc -o conftest.exe -g -O2 conftest.c -liconv -lsocket >&5
Hth,
