It appears that the header file declarations of these functions,
strcpy, exit, etc, are not being presented to the compiler.
This is suspicious since input.c contains:
...
#include <stdio.h>
#include <ctype.h>
#include <math.h>
#include <strings.h>
...
In addition, the errors above attributed to strcpy are actually
scopy function calls according to my version of input.c.


Here are some debugging ideas:

Verify that your input.c is verbatim from your dms distribution
and that it contains those includes starting at line 33.

Get the preprocessor output via
cc -DDESTLIB=\"/usr/local/lib/dms/\" -DSERVER_PATH=\"/usr/local/lib/dms/dmsd\" -Ilibpdb -E input.c
and look for the declarations of the above functions and see whats
happening on line 104 with regard to scopy.

Try to disable builtins via this compiler option: -fno-builtins


If you need more help then send explicit and verbose details
including OS and compiler versions, the -E output, the effect
of -fno-builtins, etc.
