Comment:

 I seem to be hitting a regression with 7.10.3 RC1:

 I get this when trying to link my bindings to Bullet Physics
 https://github.com/lukexi/bullet-mini

 {{{
 Preprocessing test suite 'cubes' for bullet-mini-0.1.0.0...
 [2 of 3] Compiling Types            ( test\shared\Types.hs, .stack-
 work\dist\d96ab9d9\build\cubes\cubes-tmp\Types.o )

 unknown symbol `__mingw_vsscanf'
 }}}

 The Types module is the first one that uses Template Haskell.

 I'd previously triumphantly gotten this package building with a modified
 version of 7.10.2 with the following patches applied:
 https://github.com/lukexi/ghc/commits/ghc-7.10.2-release-plus-rework-
 windows-pe-linker

 So something broke between here and there.

 So far I've tried updating my entire pacman database but that didn't seem
 to help.
