Ok, In slconfig.h, I will use:

#ifndef __os2__
# define HAVE_FINITE	1
#endif


With respect to the SLang_Error problem in slos2tty.c, instead of
using 

    if (SLang_Ignore_User_Abort == 0) _pSLang_Error = SL_USER_BREAK;

use:

    if (SLang_Ignore_User_Abort == 0) SLang_set_error (SL_USER_BREAK);

I will look at the code some more but without access to OS/2, I cannot
do much.  You may have to run it in the debugger to find out what is
going on.

I think that you need to add -lvideo to the slrnpull linker line in
the makefile.

Regarding sltest:

This is really bizarre.  In dollar.sl, change:

if ("%$1${}%"$ != "%Dollar-1%")
  failed ("%s","%$1${}%");

to 

$2 = "%$1${}%"$;
if ($2 != "%Dollar-1%")
  failed ("%s, found \"%s\"","%$1${}%", $2);

It should still fail this test but at least it will show how this is
being parsed.  After running the test again and sending me the result,
please make the following change to the push_dollar_string function in
slang.c:

Does the above change have any impact?
