Comment (by awson):

 I have fully working `-split-sections` on Windows.

 To make it possible quite recently I've fixed
 [https://ghc.haskell.org/trac/ghc/ticket/11388 a blocker bug in GHC]
 (thanks to Phyx for putting it in).

 But also we need the very latest binutils because of
 [https://sourceware.org/bugzilla/show_bug.cgi?id=19440 the bug in
 binutils] I've helped to fix just recently.

 And the final thing to make it all work are correct linker scripts
 (generated from the single `pep.sc` template), which solve
 [https://sourceware.org/bugzilla/show_bug.cgi?id=19254 section merging
 problem]. I've incorporated it in my own patched version of binutils but I
 still didn't propose the corresponding patch to upstream binutils. I have
 no much spare time at the moment, and this patch also contains an extra
 bugfix for current binutils, thus some extra work is required here, but if
 the need is urgent I'll try to wrap it in coming days.
