[Proj] compilation faults in PROJ4

[Maciek Sieczka]

Hi all!

I installed PROJ.4 (Rel. 4.4.8 2004-05-04) from source but in the log files
I found plenty of errors and warnings.

Could someone help me? My questions are:
1. are these errors serious?
2. what may be the reasons?
3. how do I get rid of them?

Forgive me please if I'm waisting your time. I have no experience in
installing from source. It's my first attempt.
My Linux is Mandrake 9.2, GCC 3.3.1, kernel 2.4.22-26mdk, bison-1.875.
Should I provide any more info please tell me.
Listed below are faults extracted from log files. COMPLETE "./configure" and
"make" logs are attached.
