Here you go. If there is a better place to put the PostmasterHandle, please
do so by all means.  Also, could enable it for EXEC_BACKEND, instead of for
WIN32, which would obviate the WIN32 #ifdefs in read/write_backend_variables
(ie. so that EXEC_BACKEND would also read/write this variable out, but to no
effect in non-WIN32 EXEC_BACKENDs).

Cheers,
Claudio

Applied, thanks.

I thought it was okay there, but should be declared in postmaster.h;
I dislike externs in .c files, because there's no chance of the compiler
catching discrepancies.

Not unless HANDLE is a typedef of wider currency than I thought...
