 Current ghc spits warnings time to time:

 {{{
 <no location info>:
     Warning: Couldn't figure out linker information!
              Make sure you're using GNU gcc, or clang
 }}}

 It's because my default locale is '''LANG=ru_RU.UTF-8''' [1]
 {{{
 ...
 gcc версия 4.8.2 (Gentoo 4.8.2-r1 p1.4-ssptest, pie-0.5.9-ssptest)
 }}}
 versus '''LANG=C'''
 {{{
 ...
 gcc version 4.8.2 (Gentoo 4.8.2-r1 p1.4-ssptest, pie-0.5.9-ssptest)
