abb4a678 Add a generic algorithm for deleting items in a container.
The sweeping pattern change in commit 238dd2fb (Use insert instead of a
loop in some cases, 2014-11-22) accidentally changed the iterator range
used on the queue in cmCTestBuildHandler::ProcessBuffer. Instead of
ending at the iterator positioned at the next newline to populate
CurrentProcessingLine, it was changed to go to the end of the queue.
This causes the line to contain newlines and possibly be cut off in the
middle of a line. Fix this regression by restoring use of the proper
end-of-line position.
The compiler in the PATH on mac is a stub for a different delegate
depending on the environment. Rather than requiring xcode-select to
change the used Xcode globally, users should be able to choose the
compiler per-session. That is possible with the DEVELOPER_DIR
environment variable.
However, the environment can change between running CMake and invoking
the build. In such cases, CMake prefers to record the relevant paths
from the environment and use them when invoking the build. That is not
currently done for the compilers on APPLE, so the compiler used is not
the one reported when running cmake:
$ DEVELOPER_DIR=/Applications/Xcode2.app/Contents/Developer/ cc --version
Apple LLVM version 6.0 (clang-600.0.51) (based on LLVM 3.5svn)
Target: x86_64-apple-darwin13.4.0
Thread model: posix
$ DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer/ cc --version
Apple LLVM version 5.1 (clang-503.0.38) (based on LLVM 3.4svn)
Target: x86_64-apple-darwin13.4.0
Thread model: posix
Update that now by querying Xcode for the correct compiler path if
the compiler located by ordinary means is located in /usr/bin.
The second hunk of commit 07d1f6fc (Features: Properly evaluate if the
compiler supports cxx_final, 2014-12-31) was a workaround for a bug in
the COMPILE_FEATURES generator expression that caused it never to return
0. Revert the workaround so we can fix the bug instead.

This topic was merged to master prematurely, so remove it.
In commit v3.1.0-rc1~113^2 (Use a more reliable regex for extracting
binary INFO strings, 2014-09-03) the matching of INFO: strings was made
more strict and no longer matches just "INFO:qnxnto". Use
"INFO:qnxnto[]" instead to conform to the new pattern.
When installing, MSMPI puts a trailing backslash in the MSMPI_BIN
environment variable. This causes trouble when concatenating in CMake
since the list separator is now escaped and no longer a list separator
due to the trailing backslash. Instead, use file(TO_CMAKE_PATH) to make
the path CMake-friendly.
Case where CPACK_CMAKE_GENERATOR value is non existent or
or contains multiple words that were not quoted was not
handled and produced a segmentation fault.
Specialize for std::map types to delete the second element from
the iterator. This is not quite general enough that it can
be used everywhere, because CMake inherits from std::map and
creates typedefs with custom comparison functors etc, which
can not use this algorithm.
