Subject: tar: don't check for getdtablesize; use AC_CHECK_FUNCS_ONCE
X-Git-Url: https://git.brokenzipper.com/gitweb?a=commitdiff_plain;h=cecb7ac8e63ff65eb73dd098796e56e0a17a3259;p=chaz%2Ftar

tar: don't check for getdtablesize; use AC_CHECK_FUNCS_ONCE

* configure.ac: Don't check for getdtablesize; no longer needed.
Use AC_CHECK_FUNCS_ONCE rather than AC_CHECK_FUNCS, for efficiency.
