Kernel compiling error on FreeBSD 5.4

[Zenobius Xavierus]

Hello :-)

I'm new to this list, and to FreeBSD alltogether.
Today i tried to compile new Kernel and i did it 'by the book'. The
problem is with compiling, i get error like:
'cc1: error: unrecognized command line option "-f"'

and then errors about "no such file or directory"

i tried several things:
- downloading sources again
- re building world

and such, with no help - always the same error

i searched for this problem on the net, but with no succes, so i'm
writing here ;-)

and now some basic info:
PC is PIII 650MHz with 256RAM, i'm using Barracuda 40Gb on IDE as
disk, ethernet is on Sis900.
OS is FreeBSD 5.4 release May 8 2005

I'm totally new to Unix like systems, that includes FreeBSD, so
please, be gentle with me ;-)

I'll answear all the additional questions, if i know, how to get the
info ;-)
I will be thankful for any help, including links and 'look into man
pages <number> you noob' ;-)

I tried everything i could think off, i'm too stupid with Unix for now
:-)

Best regards
