Hello all,

I'm a starter to programming in FreeBSD after a few years in Visual C++ and 
would like to delve deeper into it. But I have a few questions which I need 
answers. I hope it wouldn't be too much a burden to you.

I have two gccs installed, 2.95.4 (stock gcc) and 3.1.1. 

1) How do add to the standard include path to a path that I designated without 
using the -I flag or is it fixed only to /usr/local/include and /usr/include.

2) I notice that the gcc31 include files does not contain the standard C 
headers ie stdio.h, assert.h etc. Does this mean whenever I want to link to 
the header, it is sufficient to use the ones in /usr/include?

3) I notice too that there are many C++ and STL include files I'm getting 
confused on which ones to use. The files are located at /usr/include/g++, 
/usr/local/lib/i386-portbld-freebsd4.7/3.1.1/include/g++v3 and 
/usr/local/lib/i386-portbld-freebsd4.7/3.1.1/include/g++v3/backward. Can 
someone enlighten me on which one should I use. I intend on programming 
purely in C++ with the exception that in later date, I might be forced to use 
some of the C include files.

Thank you very much in advance.
