Two simd tests FAIL on Solaris, both SPARC and x86: FAIL: experimental/simd/standard_abi_usable.cc -msse2 -O2 -Wno-psabi (test for excess errors) FAIL: experimental/simd/standard_abi_usable_2.cc -msse2 -O2 -Wno-psabi (test for excess errors)
This happens because the simd headers use identifiers documented in the libstdc++ manual as reserved by system headers. Fixed as follows, tested on i386-pc-solaris2.11, sparc-sun-solaris2.11, and x86_64-pc-linux-gnu. Ok for master? As an aside, the use of vim: markers initially confused the hell out of me. As an Emacs user, I rarely use vi for much more than a pager, but when I wanted to check the lines mentioned in the g++ errors, I had no idea what was going on or how to disable the folding enabled there: // vim: foldmethod=marker sw=2 noet ts=8 sts=2 tw=80 I can't help but feel that this is just a personal preference and doesn't belong into the upstream code. For avoidance of doubt, I'd consider equivalent Emacs local variables equally inappropriate.
