The linker command is the problem.

The type of file to create is not specified, an option setting for GUI mode
is used but the program is console mode and all of the startup code, Windows
import library and the runtime library are missing.

I assume that the linker and compiler command lines are not indented as an
artifact of the news reader.  If not then indent them.

Try this instead:

ilink32 /Tpe/ap/c/x/Gn c0x32 batchuser,batchuser,,$(BATCH) import32 cw32

/Tpe  create an EXE
/ap  console mode
/c  case sensitive linking
/x  no map file
/Gn no state files
c0x32.obj  startup code
import32.lib  Windows import library
cw32.lib   runtime library

The startup code should be the first object file listed.
The runtime library should be the last library file listed

However the following will give you a smaller executable and nothing that a
C program uses is deleted.

-----------------
..autodepend

BATCH=C:\Java\1421\lib\jvm1.lib

batchuser.exe: batchuser.obj $(BATCH)

    ilink32 /Tpe/ap/c/x/Gn c0x32 batchuser,batchuser,, \
         noeh32 $(BATCH) import32 cw32

batchuser.obj: batchuser.c
    bcc32 -c -RT- -x- batchuser.c

-----------------

The backslash is a continuation char.  I used it mostly because the news
reader would otherwise word wrap the line, making it into something that
wouldn't work in a make file.

-RT-  no runtime type id. RTTI (C doesn't use it)
-x-   no exception handling, EH  (C doesn't use that either)
noeh32.lib   lib to stub any RTTI and EH links found in the libraries

The .autodepend  directive causes make.exe to check the object file records
for header files that are used against the time and date stamp of the object
file.  For instance if C:\Java\1421\include\jni.h  were modified since the
last compile, that would be detected and another compile would done during
the make.

To see the command line syntax for the linker

Start the help
Click on the Index tab
Type ILINK32 into the edit control
Click the Display button

For help on using the compiler, repeat the above with BCC32 in the edit
control.

The help file is a bit sparce on what it says about make.exe.  You can find
out a bit more at these sites:
