12# essentially interchangeable as 03 simply provides clarity to some 98
13# ambiguyity.

15# Re: Stroustrup's C++ FAQ:
16#   What is the difference between C++98 and C++03?
17#     From a programmer's view there is none. The C++03 revision of the
18#     standard was a bug fix release for implementers to ensure greater
19#     consistency and portability. In particular, tutorial and reference
20#     material describing C++98 and C++03 can be used interchangeably by all
21#     except compiler writers and standards gurus.
22#
23# Since CMake doesn't actually have an 03 mode and they're effectively
24# interchangeable then we're just going to explicitly use 03 mode in the
25# compiler when 98 is requested.
26
27# The version matching is messy here.  The std support seems to be related to
28# the compiler tweak version derived from the patch id in the version string.
