Problems compiling sqwebmail

Hi, 

I'm installing a mail server using qmail and the inter7 tools like vqadmin,
sqwebmail, etc. 

Well, the problem is that i cannot compile any of those tools.
I always get an error regarding stdlib.h (as follows). 

My system:
SuSE 9.0
gcc 3.3.1 

Thank you in advance. 

Warm Regards,
Mário Gamito
