Hello Guix!
This patch should obsolete the 'snippets' that mess with the __DATE__
and __TIME__ macros in GCC.
It is a backport of the following two commits:
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=e3e8c48c4a494d9da741c1c8ea6c4c0b7c4ff934
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=dfa5c0d3f3e23e4fdb14857a42de376d9ff8601c
...with the ChangeLog entries omitted for easier maintenance.
They *should* be functionally identical to Debians patches:
https://anonscm.debian.org/viewvc/gcccvs/branches/sid/gcc-5/debian/patches/
...but I have not verified this. Any takers?
Tested with the following shell session:
$ cat date.c
#include <stdio.h>
int main()
{
printf( "__DATE__ says: %s \n", __DATE__ );
printf( "__TIME__ says: %s \n", __TIME__ );
return 0;
}
$ ./pre-inst-env guix environment --ad-hoc address@hidden binutils glibc
[env]$ gcc date.c && ./a.out
__DATE__ says: Jan 21 2017
__TIME__ says: 11:28:06
[env]$ SOURCE_DATE_EPOCH=42 gcc date.c && ./a.out
__DATE__ says: Jan 1 1970
__TIME__ says: 00:00:42
Note: the patch is against 'master' but is intended for 'core-updates'.
