Modified Files:
configure.ag
Branch: Jan2014
Log Message:
configure.ag: with clang, disable -pthread as compiler option
(but keep it as linker option)
background is that on Mac OSX Mavericks,
"Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)"
complains about
"error: argument unused during compilation: -pthread".
Also clang 3.3 on fedora 20 appears to work fine without
-pthread as compiler option (but requires it as linker option).
