Curiously, I do not know about others who are experiencing the same
problem, however, the revisions before the referenced commit (mostly)
build just fine.

As of yet, I have not had the time and chance to even attempt to fix
this.   I have already answered Herbert the version of the build
environment (Windows 7 SP1, MinGW from July 4 (32 bit) and February 16
(64 bit), with GHC 7.6.3) -- I do not even know if that was considered
old or problematic.  I am not also sure if the developers involved in
the aforementioned change are aware of this issue and what their
