Hello, everyone.
	I  just installed gcc-2.4.5 on my sparc 10 running SunOS
4.1.3. Simple tests shows that installation is ok. But in one test which
requires using "sqrt" math function. I got the message
	undefine symbol "sqrt"
I included <math.h> in the file and the file compiled without complaints
using cc compiler.

I also tried using -I- -I/usr/local/lib/gcc-lib/sparc-sun-sunos4.1/2.4.5/include
without success.

Can somebody tell me what I did wrong? Thanks in advance.
