/* Newlib has the "f" variants of the math functions, but not the "l"
variants. TARGET_C99_FUNCTIONS is only defined if all C99
functions are present. Therefore, on systems using newlib, tests
- of builtins will fail for both the "f" and the "l" variants, and we
- should therefore not define HAVE_C99_RUNTIME. Including <limits.h>
- gives us a way of seeing if _NEWLIB_VERSION is defined. Include
- <math.h> would work too, but the GLIBC math inlines cause us to
- generate inferior code, which causes the test to fail, so it is
- not safe to include <math.h>. */
