First discovered in while building on musl 1. This is because musl-1.2.4 (9999 right now) will remove/removes the LFS compatibility hacks, like fopen64:

The gist is that bad configure tests (suffering from -Wimplicit-function-declaration) would build and link successfully because musl provided these symbols as aliases, despite not needing them (musl natively supports both LFS & time64).

To head this off, these aliases are now gone, but remain in libc.so for binary compatibility.

The proper fix is to just use the regular functions and not anything _LARGEFILE64_SOURCE As a temporary workaround you can typedef off_t to off64_t 2 to get it working.

This issue also occurs on DragonFly BSD. I found another way to fix it is to change off64_t to z_off64_t as defined in zconf.h, which has already been included by zfile.c.

@ggreer any plans on fixing this?
