Hi,

I just wanted to mention that it should probably not be too hard to
emulate the current windows behaviour in gcc/clang elf targets. Somebody
(won't be me) could add a --emulate-windows-linkage configure flag or
such.
By mapping PGDLLIMPORT to__attribute__((section(...))) it should be
relatively straightforward to put all exported variables into a special
section and use a linker script to change the visibility of the default
data, bss, rodata sections...

</crazytalk>

Greetings,

Andres Freund
