Comment:

 No, please don't do those things.

 If you want to override the compiler MacPorts uses for a port, there's no
 need to `select` that compiler nor to edit the Portfile; you can simply
 `sudo port -s install agrep configure.compiler=macports-gcc-14`. However
 compiling with gcc on macOS is generally not recommended, nor is
 overriding the compiler MacPorts chose, and I do not recommend doing that
 to try to ignore any implicit function declaration errors.

 In this case, the preferred compiler clang is able to compile the code if
 you downgrade the implicit function declaration error back to a warning.
 This is not the preferred solution to this problem but it can be used as a
 workaround on non-Apple Silicon systems. On ARM processors, implicit
 function declarations may cause incorrect program execution so I really
 don't recommend trying this on Apple Silicon systems. I have committed a
 workaround to the port to disable implicit function declaration errors and
 to mark the port as not supporting Apple Silicon. (On Apple Silicon Macs,
 MacPorts will thus install the Intel version of agrep which should work
 via Rosetta.)
