Should / must we do anything about the issue? At least Python builds
with a C89 compiler except of ssl and socket module. Those modules
include non C89 compliant header files from the OS (bluetooth and tpic).

What operating system is this on? In any case, the warnings look harmless.

I'm Ubuntu 8.10 AMD64.

These are probably all fixed by now.
