+dnl CURL_OVERRIDE_AUTOCONF
+dnl -------------------------------------------------
+dnl Placing a call to this macro in configure.ac after
+dnl the one to AC_INIT will make macros in this file
+dnl visible to the rest of the compilation overriding
+dnl those from Autoconf.

+dnl Override some Libtool tests
+dnl -------------------------------------------------
+dnl This is done to prevent Libtool 1.5.X from doing
+dnl unnecesary C++, Fortran and Java tests and reduce
+dnl resulting configure script by nearly 300 Kb.

+
+dnl Override Autoconf's AC_LANG_PROGRAM (C)
+dnl -------------------------------------------------
+dnl This is done to prevent compiler warning
+dnl 'function declaration isn't a prototype'
+dnl in function main. This requires at least
+dnl a c89 compiler and does not suport K&R.

+dnl Override Autoconf's AC_LANG_CALL (C)
+dnl -------------------------------------------------
+dnl This is a backport of Autoconf's 2.60 with the
+dnl embedded comments that hit the resulting script
+dnl removed. This is done to reduce configure size
+dnl and use fixed macro across Autoconf versions.

+dnl Override Autoconf's PATH_SEPARATOR check
+dnl -------------------------------------------------
+dnl This is done to ensure that the same check is
+dnl used across different Autoconf versions and to
+dnl allow us to use this macro early enough in the
+dnl configure script.
