If the system has 64 bit "long", then "long long" does not add new

functionality. The existing code takes advantage of this when
"typedef"ing 'longlong' in 'my_global.h'. This holds for Alpha CPUs.
If the compiler then has prototypes for C99 functions 'strtoll()' and
'strtoull()' but no implementation, the existing code in 'strtoull.c'
collides with that prototype. These collisions are avoided now.

These includes are mandatory because they check for type sizes and
functions, especially they handle tricks for Tru64 where 'long' is
64 bit already and our 'longlong' is just a 'long'.
This solves a problem on Tru64 where the C99 compiler has a prototype
for 'strtoull()' but no implementation, see "6.1 New C99 library functions"
in file '/usr/share/doclib/cc.dtk/release_notes.txt'.
