I would remove VS binaries in favor of Cygwin and MSYS2-MINGW64 ones. 
Notice that Cygwin already gives a method to install and use TL in the 
same manner one uses TL on GNU/Linux and OSX (I don't use MacTex): same 
scripts to setup PATHs, same build documents commands and so on... With 
MSYS2-MINGW64 would be the same, almost..

why then having double binaries for other platforms (i386/x86_64 for 
linux etc..)

BTW, having the same app running on different systems helps in finding 
subtle bugs..

No, the fix was to build TL using a command like this (I did this many 
months ago and don't remember exactly):

   CC=gcc ./Build...  ## force to use GCC

that helped in building ICU but then the build stopped in another step 
of the build..

In any case, my was only a suggestion. If none of the TL guys take care 
of this, let's stop to discuss it, then.
