- dnl The include of <stdio.h> is because IBM C 9.0 on AIX 6.1 supports
- dnl include_next when used as first preprocessor directive in a file,
- dnl but not when preceded by another include directive. Additionally,

- dnl Despite these two bugs, include_next is used in the compiler's

- dnl as well in this case.
