>Description:
The ./configure configuration of GCC looks for the existance of the function mempcpy, and if found sets HAVE_MEMPCPY. However the function which is actually used in gcc/fixinc/gnu-regex.c (I don't think it occurs anywhere else) is __mempcpy. This works on most systems, which have both __mempcpy and mempcpy. The latest cygwin only has mempcpy, and   shows up the bug. gcc needs a little patching to make it build.
>How-To-Repeat:

>Fix:
Look for either __mempcpy or mempcpy. Set and use separate variables,depending on the outcome. That seems the bullet proof approach.
