Comment (by barracuda156):

 Replying to [comment:4 ryandesign]:
 > Yes if you build all ports that way that could work, for those ports
 that are compatible with gcc. But on your hypothetical gcc CI worker, if
 we set `cxx_stdlib` to libstdc++, that means it can't use any of our
 prebuilt binaries that were built for libc++. MacPorts won't use any
 binaries if the MacPorts installation's `cxx_stdlib` setting doesn't match
 that of the collection of archives, not even for those ports that don't
 use C++.

 Ok, that makes sense.
 I have no idea how usable `libc++` is, and the last time it was discussed
 with Iain and Ken, it appeared that no one has an idea.

 > It feels to me like this (verifying that everything builds with gcc) is
 not our problem to solve. [https://xkcd.com/386/ Something will always be
 broken somewhere] and it's not really MacPorts' mission to fix all
 software everywhere in all build modes. I suggest we focus on fixing ports
 in the standard build configurations. There's more than enough work to
 keep everyone busy fixing implicit function declarations, implicit int
 problems, and the other usual host of problems people report when building
 with the default compiler.

 I totally agree. As I mentioned above, while I think it makes sense to
 test with GCC'' per se,'' practical meaningfulness depends on costs vs
 benefits. If costs (in whatever sense) outweigh, it is not economical to
 do it.
