test: fix build when SHOULD_FORK is false
|
|
The code in test/cairo-test-runner.c properly takes into account
|
platforms that do have fork() support, and uses the SHOULD_FORK define
|
to know whether fork is available or not.
|
|
However, this SHOULD_FORK macro is used to guard the inclusion of
|
<unistd.h>, which is needed to get the prototype of other functions
|
(namely readlink and getppid), that are used in portions of this file
|
not guarded by SHOULD_FORK.
