The 32 bit variant exports lots of underscored versions of standard
POSIX functions for historical reasons.  We didn't want to reproduce
this for the 64 bit version so the whole lot was restricted to the 32
bit export definition file.  However, __mempcpy is a GNU symbol just as
the non-underscored variant.  This has gone unnoticed when we created
the export definitions for 64 bit.

I fixed that in CVS.
