gcc does not provide it; look at newlib/libc/string/strcpy.c instead (I
look at newlib CVS, so I'm not sure which package in setup.exe provides
the newlib source snapshot used for the current build).  And as to why it
returns char* and not void, it is because the C language and POSIX require
it to do so.  And as a result, you can do things like:
strcat (strcpy (dest, source), ".exe");

Only if someone (how about you?) volunteers to write them.
