Another victim of -Werror=implicit-function-declaration being on by default now:

In 1f84e58df2799153d3c471e4e528d26baca354bc/macports-ports (master):

vm-pop3d: Fix implicit func decls; other fixes

Fix implicit function declarations.

Closes: #63346

Honor MacPorts CFLAGS, CPPFLAGS, and LDFLAGS, thus now building with the
right optimization flags and architectures, fixing universal variant.

Fix non-POSIX use of echo -n in vm-pop3d.init.

Fix syntax error in manpage. Fix manpage installation directory.

Modernize checksums.

Use notes instead of post-activate ui_msg. Remove references to Mac OS X
10.3 and earlier from notes since MacPorts requires 10.4 or later.

Remove reinplace that does nothing.
