No it doesn't. __attribute__((packed)) affects only the specified
structures.

You mentioned that you were worried about using -fpack-structs because
it would cause problems with library functions that are passed/return
structures - but using __attribute__((packed)) on your own structures
would not affect the standard library structures (such as FILE) so the
library calls would work fine.
