(Sorry about my previous, empty posting)

I am trying to compile the SKEY user authentication software for use
with the
TIS firewall toolkit, using GCC 2.70 and Linux kernel 1.3.60.

The SKEY source is based on BSD.  Make gives an the following error when
compiling skeysubr.c :

In function 'readpass':
'LCRTERA' undeclared (first use this function)
'LCRTKIL' undeclared (first use this function)

The routine which produces these errors is included below.

I've searched the header files in /usr/include for these DEFINEs, but
they
don't seem to be there. Can these be replaced by some equivalents, or is
there an include file I need to get?
