KA9Q - Compiler error ?

[Per Andersson]

I have got Microport System V/AT 2.3.0. When i try to compile Phil Karn's 
TCP/IP code it goes boom on the file slip.c : 
"slip.c", line 291:compiler error: faulty register move
*** Error code 1

Does anybody have KA9Q running under Microport ? Is there any other good
and free TCP/IP package that runs under Microport ?
