HELP PLease

[William Chan <wchan at nsr dot bioeng dot washington dot edu>]

I have problem compiling a simple C program with the -traditional switch.
It seems that the -traditional switch is not compatible with some of the
/usr/include .h files of the glibc-2.0.7 package. This was done on a 
pentinum PC running Redhat Linux 5.2 

I can compile with the -traditional switch on another linux PC running
Redhat 4.2 with libc-5.3.12. 

I notice that the /usr/include/ .h files are significantly different
between the libc-5.3.12 version and the glibc-2.0.7 version.

The problem I am facing is porting a buge C program written with the 
K&R style onto the Redhat 5.2 machine. What trick can I use with the
gcc or egcs complier ( compiler switches, etc. ) to successfully compile 
the old code without modification ?

I know that this might not be the place to ask for help. But please 
forward this message to someone in gcc.gnu.org so I can get help.
Thank you very much !!
