The following output shows the problems if __GLIBC_HAVE_LONG_LONG is
defined:

make: *** [Parser/acceler.o] Error 1
make: *** Waiting for unfinished jobs....

Do you know how to solve it if __GLIBC_HAVE_LONG_LONG is defined?

See above. I forgot to mention that it is a fix for python only and I
don't know if it should be included in the glibc. I think for other
packages to compile it would need a similar fix in other places, too.
And- so we end nowhere just because we try to solve ccc problems...
This patch was ment to demonstrate only.

Cool! I will try it. Thank you!
