35 # - Define macro to check if isfinite or _isfinite exists
37 # gmx_test_isfinite(VARIABLE)
39 # VARIABLE will be set to true if isfinite exists
41 # gmx_test__isfinite(VARIABLE)
43 # VARIABLE will be set to true if _isfinite exists
45 # gmx_test__finite(VARIABLE) - disabled since it doesn't seem to work the way the MSVC docs suggest
47 # VARIABLE will be set to true if _finite exists
