Does anybody know why I'm getting undefined reference errors for:

===============================================================
Error! E2028: _Rxframeind is an undefined reference
Error! E2028: _Rxtype is an undefined reference
file zm.obj(c:\dv\s3\prot\zm.c): undefined symbol _Rxframeind
file zm.obj(c:\dv\s3\prot\zm.c): undefined symbol _Rxtype
dmaken.exe:  Error code 129, while making '..\exe\max\maxd.exe'
dmaken.exe:  Error code 255, while making 'maxd.exe'
dmaken.exe:  Error code 255, while making 'max'
===============================================================

when "_Rxframeind" & "_Rxtype" isn't even in the
source file (c:\dv\s3\prot\zm.c) ??
