regression: PCH with msvc causing "error LNK2011: precompiled object not linked in; image may not run" #10745
Description
Hi,
As mentioned on IRC: Starting with @dcbaker 's c94c492 I see msvc builds of postgres fail when pch is enabled:
[56/56] Linking target src/bin/pg_config/pg_config.exe
FAILED: src/bin/pg_config/pg_config.exe src/bin/pg_config/pg_config.pdb

Hint on symbols that are defined and could potentially match:
__@@_PchSym_@00@UwveUklhgtivhRnvhlmUyfrowRmrmqzUhixUkligUoryktkligOzOkUxPkxsOlyq@pgport_main
__@@_PchSym_@00@UwveUklhgtivhRnvhlmUyfrowRmrmqzUhixUxlnnlmUoryktxlnnlmOzOkUxPkxsOlyq@pgcommon
The @pgport_main etc is the result of me going through the static libraries and naming them with /Yl<somename> as part of trying to debug this.
I spent a decent bit of time trying to build a reproducer, but I'm getting too tired. I suspect it's related to a static library that links to another static library. But it doesn't trigger in a simplistic reproducer unfortunately.
