I have no idea how to test this.

Mind you: a simple test program with {$linklib common}  fails for me
for either 32 or 64, wether or not I supply the path to syswow64 in
the -Fl parameter.

What is different about the build system for fpc, than just compiling
a simple test program?
Why doesn't linking fail (for all (cross)targets: win32, win64,
wince), when none of the other statically linked libs in that unit is
present on my system?

Does anybody have a common.dll in \windows\system32 at all?
None of my other 2 Win10 machines (hardware, not VM) does have any
common.dll anywhere on its system.

A google search learns that common.dll is mostly used by games?
Is the common lib that is needed a specific oracle lib?

This is so frustrating.
