     Type:  defect          |     Status:  assigned
 Priority:  Normal          |  Milestone:
Component:  legacy-support  |    Version:  2.10.7
 Keywords:                  |       Port:  legacy-support
----------------------------+----------------------------
 When linking against libMacportsLegacySupport, mkfifoat (and also mknodat)
 are unavailable because of the compiler macros here:
 https://github.com/macports/macports-legacy-
 support/blob/master/src/atcalls.c#L193-L203

 It's unclear whether this was intentional or an oversight as git-blame
 shows this was present in the original code import from 7 years ago:
 https://github.com/macports/macports-legacy-
 support/blame/master/src/atcalls.c#L193-L203
