In c.m4, AC_PROG_GCC_TRADITIONAL is defined as:
AU_DEFUN([AC_PROG_GCC_TRADITIONAL],
[AC_REQUIRE([AC_PROG_CC])],
[$0 is obsolete; use AC_PROG_CC]
)
When autoupdate runs on a configure.ac containing AC_PROG_GCC_TRADITIONAL, it
replaces it with:
AC_REQUIRE(AC_PROG_CC)
1. AC_REQUIRE cannot be used at top level in configure.ac.
2. The missing quote brackets cause AC_PROG_CC to expand inside
AC_REQUIRE(...). M4 treats the ) in yes:) inside AC_PROG_CC as the closing
parenthesis of AC_REQUIRE(...), yielding yes: in configure and a fatal shell
syntax error.
The replacement in AU_DEFUN([AC_PROG_GCC_TRADITIONAL]) should not use
AC_REQUIRE.
