New description:

 The Windows build over here spews a bunch of errors during the build like
 the ones below. All of them seem to be related to hsc2hs. The errors do
 not break the build for some reason, so the problem is not critical, but
 we should look into what's going on here.

 Note that the errors are indeterministic and the set of files affected
 varies between builds.

 Examples:

 {{{
 ghctrace.2/3.log:Failed to remove file libraries/base/dist-
 install/build/System/CPUTime_hsc_make.exe; error= DeleteFile
 "libraries/base/dist-install/build/System/CPUTime_hsc_make.exe":
