Can't find header files.

[Amit Joshi <amitjoshi86@gmail.com>]

I recently installed gcc and Anjuta for C programming. 
All dependencies have been installed. 

So whenever I try to compile a program, it returns an error saying: 
Error: stdio.h: Can't find file or directory. 

Never experienced such a problem before. 
I am using Etch and my program versions are as follows: 

gcc-3.3-base/testing uptodate 1:3.3.6-13
gcc/testing uptodate 4:4.1.1-13
gcc-4.1/testing uptodate 4.1.1-19
gcc-3.4-base/testing uptodate 3.4.6-4
gcc-4.1-base/testing uptodate 4.1.1-19
libgcc1/testing uptodate 1:4.1.1-19


anjuta-common/testing uptodate 1:1.2.4a-4
anjuta/testing uptodate 1:1.2.4a-4


Anybody experiencing similar problems?
