# There are no less than 5 standard library options:
# 1) The default, which uses an old version of the Rogue Wave std lib,
#    also available via -std=sun03.
# 2) C++03 mode + STLport, selected via the -library option.
# 3) C++03 mode plus the Apache std lib, selected via the -library option.
# 4) C++03 or C++11 in g++ compatibility mode, and GNU libstdc++3, selected via -std=c++03/11.
#
# Note that the -std, -library and -compat compiler switches appear to be largely mutually
# incompatible, and that going forward the -std switch seems to be the prefered one.
