You are assuming I have the source for the library and although I've asked nicely via email Microsoft hasn't responded
tomy requests for the source code to kernel32.dll. ;)
Regardless, even if I had the source, adding PG_MODULE_MAGIC to an arbitrary dll that has no need to know anything
aboutthe internals of Postgresql comes at a cost of much more than a one line to the source. It requires having all
therandom bits of developer headers/libraries/etc from Postgresql which has been been properly set up to work with my
particularcompiler environment. In this case, my initial attempts to wrap the functions in a shared library that I can
controlusing the headers supplied with the beta3 installer have met with little success under cygwin using -mno-cygwin
(which,in theory, should invoke mingw) and MSVC due to strange desires to include things like strings.h, libintl.h and
variousother files that don't exist.
I have an 8.1 database that has a few functions that utilize of a couple of api calls to kernel32 and another library.
I'djust like to get it working under 8.2 with minimal hassle and I'll work out the long term solution of writing a
propermodule that wraps the calls later. Since I am familiar with building Postgresql from source that is something
I'dmuch rather do after removing the check for a short-term solution.

Why? It's a one line addition to the source of the module, much less
work than trying to disable the check in the backend...
Have a nice day,
