bug#26484: feature request: add ICC support on Windows

[sav_ix]

The essential ICC feature, that it tries to be GCC on *unix and MSVC on Windows. E.g. on Windows it has almost the same compiler keys, use MSVC Linker and Librarian, Windows SDK headers, etc. For this purpose ICC uses 'VS20xx x64 Native Tools Command Prompt' to prepare environment. And thus both ICC (icl.exe) and MSVC (cl.exe) compilers are available in PATH variable during ICC run.

I didn't find any other way to make libtool use ICC, except to adopt MSVC toolchain for ICC. But I have no idea how to make them both to use the same toolchain. Perhaps, the solution could be replace all entries of 'cl.exe' with ${CC} and ${CXX} and set its default values to 'cl.exe'. But still an opened question how to make ICC use '*.cl*)' toolchain. Would be appreciated for any hints.

And even if it can be solved, it's still not much could be done without libtool Developers. Is there a chance, that someone will be engaged in this feature request?
