	* c-common.h (get_source_date_epoch): Rename to
	cb_get_source_date_epoch.
	* c-common.h (cb_get_source_date_epoch): Prototype.
	* c-common.h (MAX_SOURCE_DATE_EPOCH): Define.

gcc/ChangeLog:

2016-05-13  Eduard Sanou  <dhole@openmailbox.org>

	* doc/cppenv.texi: Note that the `%s` in `date` is a non-standard
	extension.
	* gcc.c (driver_handle_option): Call set_source_date_epoch_envvar.
	* gcc.c (set_source_date_epoch_envvar): New function, sets
	the SOURCE_DATE_EPOCH environment variable to the current time.

gcc/testsuite/ChangeLog:

2016-05-13  Eduard Sanou  <dhole@openmailbox.org>

	* gcc.dg/cpp/source_date_epoch-1.c: New file, test the proper
	behaviour of the macros __DATE__ and __TIME__ when SOURCE_DATE_EPOCH
	env var is set.
	* gcc.dg/cpp/source_date_epoch-2.c: New file, test the error output
	when parsing the SOURCE_DATE_EPOCH env var, and make sure it is only
	shown once.
	* lib/gcc-dg.exp (dg-set-compiler-env-var): New function, set env vars
	during compilation.
	* lib/gcc-dg.exp (restore-compiler-env-var): New function, restore env

	* include/cpplib.h (cpp_callbacks): Add get_source_date_epoch
	callback.
	* include/cpplib.h (cpp_init_source_date_epoch): Remove prototype.
	* init.c (cpp_init_source_date_epoch): Remove function.
	* init.c (cpp_create_reader): Initialize pfile->source_date_epoch.
	* internal.h (cpp_reader): Extend comment about source_date_epoch.
	* macro.c (_cpp_builtin_macro_text): Use get_source_date_epoch
	callback only once, read pfile->source_date_epoch on future passes.
