+The current build is statically linked, so it can't be run as part of the dash shell.

+even tried. This is making it MUCH MUCH slower.

+WASM doesn't have popen or pipes, since you can't even create other processes.
+So #ifdef UNIX is obviously not enough.
+We just patch the use of this to disable
+it explicitly.  Also the fallback code
+returns NULL instead of 0, so we fix that.
