Just to be clear about any misconceptions, this is a D-Bus library that
talks to the network. You're not ever going to be CPU bound, your
program will spend approximately all of its time waiting for IO, writing
in C is going to gain you no appreciable difference, unless perhaps
you're on an embedded device.

You already know the answer to this problem.

You can also pass -c to the compiler to delay linking. e.g. the way
Makefile.am would do this is:

gcc `pkg-config --cflags telepathy-glib` -c file1.c
gcc `pkg-config --cflags telepathy-glib` -c file2.c
gcc `pkg-config --libs telepathy-glib` -o test file1.o file2.o
