  26    of builtins will fail the "l" variants, and we should therefore not

  29    too, but the GLIBC math inlines cause us to generate inferior code,
  30    which causes the test to fail, so it is not safe.  Including <limits.h>
  31    also fails because the include search paths are ordered such that GCC's
  32    version will be found before the newlib version.  */
