the following functions in the following commits:
- atoll() in revs 1.23-1.25
- llabs() and lldiv() in revs 1.22
- strtoq() and strtouq() in revs 1.18
C99 functions must not be declared in C90/POSIX.1-1990 sections, and
"long long" must not be exposed to compilers that don't support it.
Fixed style bugs (mainly misindentation and disorder) related the
following functions in the following commits:
- atoll() in revs 1.23-1.25
- getprogname() in rev.1.21
- sranddev() in revs 1.19-1.20
- strtoq() and strtouq() in rev.1.13
- user_from_uid() in rev.1.1
Breakage of K&R and C90 support used to be avoided by conditializing the
"long long"s for strtoq() and strtouq() on __STRICT_ANSI__, but the
conditionals should have gone away in rev.1.13 when the "long long"s went
away (the problem was moved to the places that declare quad_t and u_quad_t).
