Re: [patch] Clean up detection of SJLJ exceptions in target libraries


This patch fixes an issue preventing mingw-w64 i686 dwarf2-eh
bootstrapping described at:

http://sourceforge.net/p/mingw-w64/mailman/message/34101954/

I'm assuming this has more to do with switching away from the current
sjlj configuration method since configuring gcc with
"--disable-sjlj-exceptions --with-dwarf2" still suffers the same
issues.  Building with simply "--with-dwarf2" instead, however, now
works fine.  I'm not sure whether or not a bug has been created for it
and if one needs to be.

Much appreciated,
Matt
