Build Windows DLLs with `-Wl,--export-all-symbols` This is not the most elegant, but will match the SOs in exporting everything for now. Later we can refine what is public/private to clean up the interface. 2024-01-09 17:41:42 +00:00			`ifdef HOST_OS`

Fix OpenBSD build with Makefiles OpenBSD dynamic libraries never link to libc directly. Instead, they have undefined symbols for all libc functions they use that ld.so resolves to the libc referred to in the main executable. Thus, disallowing undefined symbols will always fail (cherry picked from commit c49bff2434971d693b03525622082a81b5ed75eb) 2024-10-24 21:24:47 +00:00			`ifeq ($(patsubst openbsd%,,$(HOST_KERNEL)),)`
