Yes, it's YAMB.  I reported it about 9 months ago (when microport was
1.3) and did again on BIX (Byte Information eXchange) few manths ago.  
Seems they admitted it as a bug, but havn't put it on bug list,yet.
'dleu' told us (on BIX) they will *TRY TO* fix this bug in next version.

BTW, I tried to 'yacc' same yacc-src-code on diffrent system (very old
VENIX/86 on pc/xt!) and transfer back to microport, then 'cc' it.
It DID work!  If you have other unix system handy, give it try.
