| 7 | dnl ones recommended to be in stdint.h in the C99 standard (e.g. uint32_t). |
| 8 | dnl This is a dumbed-down version of the macro of the same name in the file |
| 9 | dnl ac_need_stdint_h.m4 which is part of the ac-archive, available at |
| 10 | dnl <URL:http://ac-archive.sourceforge.net/> (also, another macro |
| 11 | dnl AC_CREATE_STDINT_H by the same author). This version is not as smart, |
| 12 | dnl but works on older autoconf versions and has a different license. |

| 15 | dnl This is similar to _AC_CHECK_TYPE_NEW (a.k.a. new syntax version of |
