* options.c (gfc_init_options): By default, allow legacy extensions
but warn about them.
(gfc_post_options): Make -pedantic warn about legacy extensions
even with -std=legacy.
(gfc_handle_option): Make -std=gnu follow the default behaviour
of warning about legacy extensions, but allowing them. Make the
new -std=legacy accept everything and warn about nothing.
* lang.opt (std=legacy): New F95 command line option.
* invoke.texi: Document both -std=f2003 and -std=legacy.
* gfortran.texi: Explain the two types of extensions and document
how they are affected by the various -std= command line options.

* gfortran.h (gfc_option): Add flag_f2c.
* invoke.texi: Document '-ff2c' command line option. Adapt
documentation for '-fno-second-underscore' and '-fno-underscoring'.
* lang.opt (ff2c): New entry.
* options.c (gfc-init_options): Set default calling convention
to -fno-f2c. Mark -fsecond-underscore unset.
(gfc_post_options): Set -fsecond-underscore if not explicitly set
by user.
(handle_options): Set gfc_option.flag_f2c according to requested
calling convention.
* trans-decl.c (gfc_get_extern_function_decl): Use special f2c
intrinsics where necessary.
(gfc_trans_deferred_vars): Change todo error to assertion.
* trans-expr.c (gfc_conv_variable): Dereference access
to hidden result argument.
(gfc_conv_function_call): Add hidden result argument to argument
list if f2c calling conventions requested. Slightly restructure
tests. Convert result of default REAL function to requested type
if f2c calling conventions are used. Dereference COMPLEX result
if f2c cc are used.
* trans-types.c (gfc_sym_type): Return double for default REAL
function if f2c cc are used.
(gfc_return_by_reference): Slightly restructure logic. Return
COMPLEX by reference depending on calling conventions.
(gfc_get_function_type): Correctly make hidden result argument a
pass-by-reference argument for COMPLEX. Remove old code which does
this for derived types.
