 This is (almost) great timing as I've just spent half an hour on this
myself and was just about to post here asking how did you manage to make
this work.

 Because the C++ backend (libexec/gcc/i686-w64-mingw32/6.3.0/cc1plus.exe)
can't find libwinpthread-1.dll which is in the directory of the driver
(bin).

 This is one solution. Another one would be to copy libwinpthread-1.dll to
/opt/lmi/local/bin, just as is already done for a couple of other DLLs
(i.e. update compiler_runtime_files make variable to include it). This
seems to work too and seems less intrusive.

 In any case, I am reassured to know that this is not something specific to
my Cygwin installation or configuration, so thanks for posting this.
