As far as I can tell, these two functions were not tested for by configure:

checking for enabled long long I/O support... yes

Here is config.log:

configure:3626: checking for enabled long long I/O support
configure:3637: /xxx/gnu/gcc-3.1/objdir/gcc/xgcc -B/xxx/gnu/gcc-3.1/objdir/gcc/
-B/usr/local/hppa1.1-hp-hpux10.20/bin/ -B/usr/local/hppa1.1-hp-hpux10.20/lib/ -i
system /usr/local/hppa1.1-hp-hpux10.20/include -c -g -O2  conftest.c 1>&5
configure:3654: /xxx/gnu/gcc-3.1/objdir/gcc/xgcc -B/xxx/gnu/gcc-3.1/objdir/gcc/

system /usr/local/hppa1.1-hp-hpux10.20/include -c -g -O2  conftest.c 1>&5

Hmmm.  The configure doesn't link the program.  With C, it isn't an error
to have an undeclared function.  If you used g++, you would get an error:

40 (hiauly1)dave> g++ -g -c -O2 strtoll.c
strtoll.c: In function `int main()':
strtoll.c:3: `strtoll' undeclared (first use this function)
strtoll.c:3: (Each undeclared identifier is reported only once for each
   function it appears in.)
