4Subject: [PATCH 16/16] Check for clang before checking gcc version
5
6Clang advertises itself to be gcc 4.2.1, so when compiling this test
7here fails since gcc < 4.4.5 did not support -static-libstdc++ but thats
8not true for clang, so its better to make an additional check for clang
9before resorting to gcc version check. This should let clang enable
10static libstdc++ linking
