Hi Manuel,

can you look into Work/build.log:

After "=== configuring in icu-build", there ought to be
"checking build system type..." and "checking host system type...".
What are they? In particular is host system type "i586-mingw32msvc" or
"i586-pc-mingw32msvc"?

BTW: Using '--build=i686-linux-gnu --host=i386-pc-mingw32' for gcc cross
compiler I have no such problem.

Might be worth it, but may also be just a waste of time.  The only
difference between the TL build procedure and the one described readme.html
is that TL directly uses configure and not runConfigureICU.

================

A quite different point.  If you configure with '--disable-xetex' and
'--disable-bibtexu' the icu libraries are not used. Can you then build
everything else?
