 The proprietary Binary component of the current drivers: source/ltmdmobj.o
 was compiled with version 2.95 gcc.  Red Hat 8.0 and Mandrake 9.0 releases utilize 
 a version 3.2 gcc compilers. 
 Compiling with versions gcc=3.2 is successful,
 although build_module is equipped with a Warning against this practice.

 Simple driver insertion fails with a message like: 
----begin error----
% insmod lt_modem
Using /lib/modules/2.4.18-14/ltmodem/lt_modem.o
/lib/modules/2.4.18-14/ltmodem/lt_modem.o: The module you are trying to
load (/lib/modules/2.4.18-14/ltmodem/lt_modem.o) is compiled with a gcc
version 2 compiler, while the kernel you are running is compiled with
a gcc version 3 compiler. This is known to not work.
-----end error-----

 But as related by Jos Vos in 
    http://phep2.technion.ac.il/linmodems/archive/msg04510.html
 loading with forcing (-f) by Root is effective
    insmod -f lt_modem
    insmod -f lt_serial
 Then check for insertion with:
    lsmod

 If driver insertion is successful, the forcing can be automated
 by putting the lines (credit to Bhaskaran Raman) :
    if `gcc -dumpversion | cut -d. -f1` == 3 
    install lt_modem  /sbin/insmod --force lt_modem
    install lt_serial /sbin/insmod --force lt_serial
    endif

 into ONLY ONE of the following files (within the ltmodem  sub-section), 
 depending on your particular Linux installation, in order of preference:
    /etc/modutils/ltmodem
    /etc/modutils/aliases
    /etc/modules.conf

 Then inform your System of the edit for Debian like Systems with
    update-modules
 which rewrites and reads /etc/modules.conf . For other System types 
    depmod -a
 re-reads the edited      /etc/modules.conf .

 Thereafter module loading should behave as previously.
 For the ltmodem drivers loading,
 it should suffice to either start a ppp session or
    modprobe lt_serial
      
 This problem will be obviated when source/ltmdmobj.o compiled with 
 a version 3.nn gcc is provided by Agere Systems, Inc.
