(Modified) Patch request for PostgreSQL 7.4 for HP-UX IA-64

Subject: PostgreSQL Patch: Modified Test-and-set routine for HP-UX (IA-64) specifically for the HP-C compiler

With reference to Tom Lane's response to our previous patch request (at
http://archives.postgresql.org/pgsql-bugs/2003-10/msg00149.php)
this is a modified and more focussed patch request for PostgreSQL for for HP-UX
11i V2 for the Intel Itanium architecture (known to the PostgreSQL code as
IA-64).

The patch is required for HP-UX customers who want to compile the product
with the HP-C compiler. We have a significant number of HP-UX users who want
to build PostgreSQL on the IA-64 platform, but with the HP-C compiler.

The primary content of this patch is inline tas code that will build with HP-C.
There is one side-effect (described later) of using HP-C, also addressed by the
patch.

The target version is PostgreSQL 7.4.

We have downloaded the source (on Nov 18), applied the patch, and have tested
it successfully.

Note: HP-UX users building the product with the gcc compiler can use
the 7.4 version (or even the 7.3.4 version).

Details for the patch are in the attached template file. A summary is provided
here:

Version: PostgreSQL 7.4

Files modified:

1. s_lock.h: modified with inline tas code for the HP-C compiler

2. genbki.sh: a one-line change that fixes a string concatenation problem with the
HP-C compiler (specific to included .c files).
