I tried to download the new trunk version of fpc via fpcupdeluxe and
when I run ppc1.exe I get an error that symbol
CoWaitForMultipleObjects is unknown, i use Win7 x64 system, compiler
no longer supports win7 or what?

I’m a little guilty of insisting that an open array should be used,
maybe without that the patch would already be accepted. But I still
consider it a good idea, as the open array-based interface is fully
compatible with the Delphi interface based on a dynamic array, that’s
the reason why open arrays exist after all. (Or the devs could change
const HandleObjs: array of THandleObject back to const HandleObjs:
THandleObjectArray if they really want to.)

this theme problem is not about open arrays but what
rtl\win\systhrd.inc file got patch with Win7 incompatible code (20 may
2023 date)

No, only using them makes them incompatible.

marcov, even empty application is incompatible because it uses “basic
events”, and if you use THandleObject.WaitForMultiple, things are even
worse as it is completely broken.

Yes, maybe I didn’t say it clearly, but it caused an explosion for me
that automatic dynamic linking completely blocks the launch of the
compiler on win7.

agree. i don't want to use that functions but AT LEAST we have it in
compiler which will not work.
