Branch: MAIN
CVS Tags: HEAD
Changes since 1.5: +1 -1 lines
FILE REMOVED
Add runtime detection of active GCC on Linux (bug \#406163) and FreeBSD (bug \#409269).
Remove unnecessary headers on FreeBSD, bug \#417171.
Run time detection enables Clang to build C++ code without USE=system-cxx-headers, so no longer set it by default
