strtoll and strtoull are already defined in SUA 6.0 but with a different prototype. The build will fail because strto[u]ll.c includes stdlib.h which also comes with defines for these two functions causing the function declaration to not even be valid C-code.
I have attached a patch to resolve this issue.

This patch was not a good idea. I'll look into another fix.
Here is a new patch that changes suacomp so that strto[u]ll.c is using C99 prototypes which are used in SUA 6.0.
