Small patch to get bash 2.05b to compile on HP/UX 11.00

[Petter Reinholdtsen]

Here is a first try for a patch to get bash 2.05b to compile out of
the box on HP/UX 11.00.  It is a workaround for the horribly broken
strtold() on HP/UX 11.0.  This will make the code use strtod()
instead.

This code fragment will fail to compile because of the broken return
type for strtold():

  #include <stdlib.h>],
  int main() {
    long double ret; char *foo, bar;
    ret = strtold(foo, &bar);
  }

Please include it in the next version of bash.
