It is very strange, but the current AIX does not seem to support a 32-bit call to posix_fadvise() when _LARGE_FILES is defined.
http://www-01.ibm.com/support/docview.wss?uid=isg1IV56170

Until it is supported, we need this ugly patch to not call posix_fadvise()....

FYI, detailed explanation follows:
The 2nd and 3rd arguemnts to posix_fadvise() are the off_t type. If _LARGE_FILES is defined, off_t is defined as long long int on the caller side. This means the 2nd and 3rd arguments are passed using two registers each on a 32-bit environment. However, the callee side does not support _LARGE_FILES, so off_t is assumed to be long int, which is passed using one register. As a result, the callee side can not receive a correct value for the 4th argument, int advice, throwing EINVAL.

I am not familiar with autoconf, but shoundn't this be ac_cv_func_posix_fadvise, not ac_cv_posix_fadvise?
