[PATCH] Get bash 3.0 compiling on HP-UX 11.00

[Petter Reinholdtsen]

bash 3.0 fail to compile on HP-UX 11.00 (PA-RISC).  There are two
problems with the strftime.c file:

 - 'inline' is already defined, it is not allowed to define it again
   with conflicting definition.

 - 'timezone' is type 'long' (and not the default 'int'), and altzone
   is an unknown symbol.

This patch fixes these problems by only defining inline if it isn't
already defined, and by adding a special case for hp-ux regarding
timezone/altzone.  I guess time offset calculations will be wrong
depending on daylight.  I do not know HP-UX well enough to tell.

It compiled and was able to run when I had applied this patch.  I'm
not sure if this is the correct way to fix the problem.
