* c-common.c (get_source_date_epoch): New function, gets the environment
variable SOURCE_DATE_EPOCH and parses it as long long with error
handling.
* c-common.h (get_source_date_epoch): Prototype.
* c-lex.c (c_lex_with_flags): set parse_in->source_date_epoch.
gcc/ChangeLog:

libcpp/ChangeLog:
2016-04-28 Eduard Sanou <dhole@openmailbox.org>
Matthias Klose <doko@debian.org>
* include/cpplib.h (cpp_init_source_date_epoch): Prototype.
* init.c (cpp_init_source_date_epoch): New function.
* internal.h: Added source_date_epoch variable to struct
cpp_reader to store a reproducible date.
* macro.c (_cpp_builtin_macro_text): Set pfile->date timestamp from
pfile->source_date_epoch instead of localtime if source_date_epoch is
set, to be used for __DATE__ and __TIME__ macros to help reproducible
builds.
