Apache Flags - HP-UX

[Rahul Kohli]

Hi,

I have developed a C++ application for HP-UX - Apache Web Server. 

Actually my requirement is: 

I want for all Apache versions my code flow should be different then for Apache 1.3.19 
based IBM HTTP Server and I want to use the same executable with same Makefile.

For e.g:
if (flag1)
        Code1;
else 
        Code2;

For IBM Apache 1.3.19, I want the flag1=true and for other Apache web servers it to be 
false.

How can I achieve this?  Are there some Apache version specific flags that can be 
checked at runtime.

Thanks,
