tests: define __STDC_LIMIT_MACROS
With glibc 2.16, we get following build error when building jack2: [193/247] cxx: tests/iodelay.cpp -> build/tests/iodelay.cpp.4.o ../tests/iodelay.cpp:171:43: error: 'UINT32_MAX' was not declared in this scope ../tests/iodelay.cpp:171:55: error: 'UINT32_MAX' was not declared in this scope ../tests/iodelay.cpp:172:44: error: 'UINT32_MAX' was not declared in this scope ../tests/iodelay.cpp:172:56: error: 'UINT32_MAX' was not declared in this scope In glibc 2.17 or older version, Header <stdint.h> defines these macros for C++ only if explicitly requested by defining __STDC_LIMIT_MACROS. We can't use <cstdint> since it requires C++11 standard. This build issue found by Buildroot autobuilder. http://autobuild.buildroot.net/results/369/369ce208ffea43dad75ba0a13469159b341e3bf5/ Signed-off-by: Rahul Bedarkar <rahul.bedarkar@imgtec.com>
