Comment (by cjones051073):

 I do not see what the problem is here.

 1. The if statement is correct. The configure option needs to be applied
 to both the main gccX port but also the libgccX sub-port, and the current
 check does this.

 2. I do not understand what you mean by the above doing nothing ? The
 variant correctly ensures the -with-gxx-libcxx-include-dir option is
 applied. e.g. from `sudo port -d configure gcc13`

 So, in short, I don't see anything wrong here.
