Subject: [jira] [Commented] (HDFS-1619) Does libhdfs really need to depend
 on AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T and AC_TYPE_UINT16_T ?

Allen Wittenauer commented on HDFS-1619:
----------------------------------------

Shouldn't we test for c99 then?  In the case of Sun's compilers, it definitely requires a flag.

> Currently configure.ac uses AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T and AC_TYPE_UINT16_T and thus requires autoconf 2.61 or higher. 
> This prevents using it on such platforms as CentOS/RHEL 5.4 and 5.5. Given that those are pretty popular and also given that it is really difficult to find a platform
> these days that doesn't natively define  intXX_t types I'm curious as to whether we can simply remove those macros or perhaps fail ONLY if we happen to be on such
> a platform.
