 aclocal.m4 has a block of code that checks to see if gcc supports -fno-
 stack-protector and adds that flag if so.  That ends up in
 /usr/lib/ghc/settings, gets passed in whenever C bits get built, etc.  I
 see that block was moved into place in 2010, but is even older than that.

 What I'm wondering is: is that still necessary to do, or do ghc and stack
 protection play nicely together now?  I've searched around but can't find
 much information about it (searching for ghc and stack is a lot harder
 since that program appeared).  The one thing I've found is:

 https://gitweb.gentoo.org/repo/gentoo.git/commit/dev-
 lang/ghc?id=8cee49e4a6c8d9ec80faa4054b621467450d3ebb

 I'm in charge of building Haskell-related stuff for a semi-private Linux
 distribution and just want to make sure I'm getting things right.
