# The Fujitsu compiler offers both a 98 and 03 mode. These two are

# ambiguyity.

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