This isn't an objection, since upgrading auto* for the toolchain can be complicated, but note that AC_PROG_CC_C99 is obsolete in Autoconf 2.70 and instead AC_PROG_CC enables C11 mode if supported. (So moving to the latest Autoconf and Automake releases would supersede this change.) -- Joseph S. Myers joseph@codesourcery.com
