Description

When compiled with EDG eccp 3.10 (and possibly prior versions of the same), a number of example programs fail to link with the error below:

As an aside, redirecting nm's stderr to /dev/null in $EDG_BASE/edg_eccp_config silences the nm noise.

[Martin Sebor]

Actually, only three example programs fail with this error: codecvt.cpp, collate.cpp, and ctype.cpp. The error appears to be caused by the fact that the names of the example source files are the same as the names of the library source files that define the corresponding facets. Seems like a compiler bug... Since the errors can be worked around by renaming the program .cpp files I'm lowering Priority to Minor and deferring the issue for 4.2.1.

Now that 4.2.0 is released, set Affects Version(s) accordingly.

In total, three examples are affected by this problem: codecvt.cpp, collate.cpp, and ctype.cpp:

Deferred until 4.2.2.
