-Subject: [PATCH] print_pager: add missing includes
-
-When building with musl:
-
-  print_pager.h:33:25: error: unknown type name 'pid_t'
-     33 | extern void wait_to_die(pid_t process);
-        |                         ^~~~~
-  print_pager.h:34:25: error: unknown type name 'pid_t'
-     34 | extern FILE *exec_pager(pid_t *process);
-        |                         ^~~~~
-
-print_pager.h uses pid_t and FILE, so add the required #includes to
-ensure that these are defined.
