Hi,

Since last week wasi system unit calls fd_prestat_get, which is not yet implemented:

pas2js git, unit packages/wasi/wasienv.pas :

function TPas2JSWASIEnvironment.fd_prestat_get(fd, bufPtr: NativeInt
  ): NativeInt;
begin
  console.log('Unimplemented: TPas2JSWASIEnvironment.fd_prestat_get');
  Result:=WASI_EBADF;
end;

Was some file not committed?
