* longlong.h (add_ssaaaa) [__arm__]: Do no use asm if thumb code
generation is enabled. This is bug#1202. Reported for gpg 1.4.
NB: ChangeLog files are no longer manually maintained. Starting
on December 1st, 2011 we put change information only in the GIT
commit log, and generate a top-level ChangeLog file from logs at
"make dist". See doc/HACKING for details.
