dnl Look for a header file that defines size-specific integer types like the
dnl ones recommended to be in stdint.h in the C99 standard (e.g. uint32_t).
dnl This is a dumbed-down version of the macro of the same name in the file
dnl ac_need_stdint_h.m4 which is part of the ac-archive, available at
dnl <URL:http://ac-archive.sourceforge.net/> (also, another macro
dnl AC_CREATE_STDINT_H by the same author). This version is not as smart,
dnl but works on older autoconf versions and has a different license.
dnl AX_CHECK_DEFINED_TYPE ( TYPE, FILE, ACTION-IF-FOUND, ACTION-IF-NOT-FOUND )
dnl This is similar to _AC_CHECK_TYPE_NEW (a.k.a. new syntax version of
dnl AC_CHECK_TYPE) in autoconf 2.50 but works on older versions
