[Groff] looking for defs.h and stringclass.h

[michael lindenmeyer]

Compiling groff.cpp with borland 4.0 and discover that there is no defs.h 
header in /src/include. In addition, stringclass.h, that is in /src/include is 
not recognized by the compiler. Can someone provide a resource for defs.h 
and/or explain why stringclass.h is not recognized by the compiler?
 
Thanks.
