Currently, there are formal tests for changes in the libstdc++ ABI,

and in addition informal testing procedures. Work to develop these

tests is ongoing.

Testing for GNU C++ ABI changes is composed of two distinct areas:

testing the C++ compiler (g++) for compiler changes, and testing the

C++ library (libstdc++) for library changes.

There is a formal method for checking the compiler parts of the C++

<p>
|

If the 'gnu' locale model is being used, the following locales
|
||||
are used and tested in the libstdc++ testsuites: en_HK, en_US,
|
||||
fr_FR, fr_FR@euro, de_DE, de_DE@euro, ja_JP.eucjp, and
|
||||
it_IT. Failure to have the underlying "C" library locale
|
||||
information installed will mean that C++ named locales for the
|
||||
above regions will not work: because of this, the libstdc++
|
||||
testsuite will not pass the named locale tests. If this isn't an
|
||||
issue, don't worry about it. If named locales are needed, the
|
||||
underlying locale information must be installed. Note that
|
||||
rebuilding libstdc++ after the "C" locales are installed is not
|
||||
necessary.

support for locales, do only one of the following: </p>
