Tests: warning: ISO C90 does not support ‘long long’ [-Wlong-long]

While running "make check" I get these warnings:

test/test-platform-output.c: In function ‘run_test_platform_output’:

I presume a higher standard (-std= option) needs to be used at least for tests.

I think this issue can be closed. It's a duplicate of #850
