The function absolute_filename() lib-src/etags.c has two invalid calls to strcpy() with overlapping arguments. It's undefined C that often happens to work, but breaks very badly for at least gcc 4.4.2 and glibc 2.11 on x86_64, which is default for Fedora 12.

The attached patch replaces the bogus strcpy() calls with calls to memmove().
