 Thanks for running that. I wanted to check whether gcc could find
 `sys/errno.h`, and it seems that it can. Ignore the `VFLAGS` fix; I don't
 think that it will make a difference.

 Until I find a better solution, would you mind removing the `errno`
 reference in vlang? It's only required for a
 [https://github.com/vlang/v/commit/8f6fec4364b5eaf00a5ae07c70517cc3fc74e33b
 specific concurrency example], and so shouldn't make that much of a
 difference during runtime:

 {{{
 > sudo port fetch vlang
 > sudo sed -i "" "10d" "$(port work
 vlang)/v-weekly.2022.13/vlib/sync/sync_darwin.c.v"
 > sudo port -o install vlang
 }}}

 Just to note that this is not a fix, it's just a temporary patch until I
 find something better. This problem is a bit tricky :)
