Boris Kolpackov updated XERCESC-1917:
-------------------------------------
Priority: Minor (was: Major)
Issue Type: Improvement (was: Bug)
FYI, there are no plans to release any more versions in the 2-series. In the
3-series we use a similar workaround but in a cross-platform way, so this patch
is not easily applicable. Also, what is the problem with having these symbols
visible in the Xerces-C++ library?

> Components: Build

> Environment: linux x86_64 gcc
> Reporter: George Gensure
> Priority: Minor

> The stricmp and strnicmp prototypes provided as a workaround for those
> functions missing in gcc/glibc installations are defined in the global scope
> and without extern "C" qualifiers. As a result, these are the *only*
> non-xerces_2_8 namespaced functions exposed by the shared library on linux.
> I recognize that the compiler workarounds are included prior to the xercesc
> namespace definition, and as a compromise I'd be happy to see the definitions
> have their prototypes changed to be within an extern "C" block, as well as
> __attribute__((visibility("hidden"))) applied to their definitions. The
> following diff applies cleanly to the 2.8 release and corrects my problem:
