| Subject: [PATCH] configure.ac: use pow() instead of matherr() for libm check |
| |
| In certain configurations of uClibc, the matherr() function may not be |
| provided by the C library, which makes the current configure.ac check |
| for libm fail. However, iprutils does not use matherr(), so using this |
| function for the test makes little sense. |
| |
| This patch adjusts configure.ac to test for pow() instead, which is |
| actually used by iprutils, and more commonly available, including in |
| uClibc. |
