There is:
#if (TEST_FTRUNCATE64 == 1)
/* ftruncate64() call */
#endif
#if (TEST_FTRUNCATE64 == 2)
/* ftruncate64() call */
#endif
#if (TEST_FTRUNCATE64 == 3)
/* ftruncate64() call */
#endif
And the "#define ftruncate64" is needed for all 3 test cases to ensure
that every test case would call that __mingw_ftruncate64 implementation.
Therefore I added above #ifdef TEST_FTRUNCATE64 which will cover all 3 test
cases.
