Fix compiler warnings about unused value in TRACE macros.
* src/debug.h: Change macros to not have a literal 0 as last expression of the comma operator. * src/debug.c (_gpgme_debug_frame_end): Return 0. (_gpgme_debug): Return 0.
Instead of using
foo(), 0
for the trace macros we let foo() return 0 instead.
