+# AC_CHECK_KLIBC
+# --------------
+# Check if the user wants KLIBC support enabled. If so, set KLIBC=yes and
+# fill in KLIBC_PREFIX, KLIBC_BINDIR, KLIBC_SBINDIR, KLIBC_LIBDIR and
+# KLIBC_INCLUDEDIR. CC is also set to the proper klcc executable.
+# NOTE: This should be called before AC_PROG_CC, and before header, function
+# or type checks.
