Did you notice what the strcpy() expands to?  Check line 10469 of
we_wind.i: you'll find a switch statement, as well as some calls to
strlen().  Unfortunately, strlen is not a function in the current
scope: the function argument named `strlen' hides the standard
function strlen().  I believe this is well-defined, and glibc should
call __strlen or such instead, but I'm no C language lawyer.

Maybe you should report this as a bug to the maintainers of glibc...
Unless some of them is listening to this discussion :-)

Anyway, I'd recommend xwpe people to rename the function argument;
it's bad practice to redefine well-known names :-)
