Problems with Informix 4GL under ISC

[robert.m.zachok]

I'm hoping that someone out there can help me.  I'm trying to create
a customized version of an Informix 4GL runner (fglgo), under ISC UNIX
2.0.2 (and ISC Software Development System V2.0), by linking
in some "C" language functions of my own.
  Informix has a utility (cfglgo) that compiles and links user specified
functions along with 4gl libraries into a version of fglgo that permits
4gl access to "C" functions
When I run cfglgo, the following symbols are undefined:
(_fltused, _ftoc, _fac, _ftol & ftime).  This is true even if I try
to build a standard runner, without any user defined functions.

The version of 4gl that I'm using is 2.10.03K for a Compaq Deskpro
'386 & AT&T Unix 5.3.  I've tried to get help from Informix support,
but it seems that ISC is not among the *NIX vendors supported.

I'd appreciate any help from anyone who has successfully built a
custom 4gl runner in this environment and can let me know what
Informix 4GL product configuration they have.  I can't believe that
I'm the only ISC user that has tried this.  If there is sufficient
interest, I'll summarize the results.
