cede950232 convert each use of gfc_free (p) to free (p) 
Do that by running this command:
  perl -pi -e    's/\bgfc_free ?\(/free (/' \
    $(git grep -El '\bgfc_free ?\(')
which also corrects the few uses that lacked a space between
the function name and the open parenthesis.
Manually undo the change to the function definition itself
and its prototype.  They'll be removed next.

2009-08-01  Paul Thomas  <pault@gcc.gnu.org>

	PR fortran/40011
	* error.c : Add static flag 'warnings_not_errors'.
	(gfc_error): If 'warnings_not_errors' is set, branch to code
	from gfc_warning.
	(gfc_clear_error): Reset 'warnings_not_errors'.
	(gfc_errors_to_warnings): New function.
	* options.c (gfc_post_options): If pedantic and flag_whole_file
	change the latter to a value of 2.
	* parse.c (parse_module): Add module namespace to gsymbol.
	(resolve_all_program_units): New function.
	(clean_up_modules): New function.
	(translate_all_program_units): New function.
	(gfc_parse_file): If whole_file, do not clean up module right
	away and add derived types to namespace derived types. In
	addition, call the three new functions above.
	* resolve.c (not_in_recursive): New function.
	(not_entry_self_reference): New function.
	(resolve_global_procedure): Symbol must not be IFSRC_UNKNOWN,
	procedure must not be in the course of being resolved and
	must return false for the two new functions. Pack away the
	current derived type list before calling gfc_resolve for the
	gsymbol namespace.  It is unconditionally an error if the ranks
	of the reference and ther procedure do not match. Convert
	errors to warnings during call to gfc_procedure_use if not
	pedantic or legacy.
	(gfc_resolve): Set namespace resolved flag to -1 during
	resolution and store current cs_base.
	* trans-decl.c (gfc_get_symbol_decl): If whole_file compilation
	substitute a use associated variable, if it is available in a
	gsymbolnamespace.
	(gfc_get_extern_function_decl): If the procedure is use assoc,
	do not attempt to find it in a gsymbol because it could be an
	interface. If the symbol exists in a module namespace, return
	its backend_decl.
	* trans-expr.c (gfc_trans_scalar_assign): If a derived type
	assignment, set the rhs TYPE_MAIN_VARIANT to that of the rhs.
	* trans-types.c (copy_dt_decls_ifequal): Add 'from_gsym' as a
	boolean argument. Copy component backend_decls directly if the
	components are derived types and from_gsym is true.
	(gfc_get_derived_type): If whole_file copy the derived type from
	the module if it is use associated, otherwise, if can be found
	in another gsymbol namespace, use the existing derived type as
	the TYPE_CANONICAL and build normally.
	* gfortran.h : Add derived_types and resolved fields to
	gfc_namespace. Include prototype for gfc_errors_to_warnings.
