Hello,

In the glib source, only this C source file contains C++ comments:

gobject/tests/threadtests.c

These lines are affected:

$ grep -n "//" glib-2.20.1/gobject/tests/threadtests.c.bak
67:      g_atomic_int_add (&mtsafe_call_counter, 1); // real call count update
68:      g_thread_yield(); // let concurrent threads corrupt the unsafe_call_counter state
69:      unsafe_call_counter = 1 + saved_unsafe_call_counter; // non-atomic counter update
172:    ; // neds unit test framework initialization: g_test_bug ("race initializing properties");

It makes the IBM XL C Compiler (the 'native' non-free compiler on the AIX platform) stop compiling glib with syntax error. If you could remove or replace these comments, compilation would otherwise be error-free on these platforms: AIX 5.3 and 6.1. ;-)

regards
LGee
