Eli Collins commented on HDFS-1619:
-----------------------------------
We don't need to set AC_PROG_CC_C99 because we don't actually use any c99
features in libhdfs. However libhds already uses (ie requires) stdint.h so we
don't need set AC_TYPE* because we get these already from our stdint.h
dependency. AC_TYPE* were probably not removed when stdint.h was introduced.
Therefore I think the current patch is good to go as is. Make sense?
> Does libhdfs really need to depend on AC_TYPE_INT16_T, AC_TYPE_INT32_T,
> AC_TYPE_INT64_T and AC_TYPE_UINT16_T ?

> 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.
