[PATCH 2/5] gdi32: Link directly to user32.
by Jacek Caban Feb. 17, 2022

Feb. 17, 2022

On Windows, loading gdi32.dll causes user32.dll to be loaded. It's important for win32u, which is not fully functional until user32 sets KernelCallbackTable.

[PATCH 1/5] user32: Delay load setupapi.
by Jacek Caban Feb. 17, 2022

Feb. 17, 2022

This reverts 50aeb5e777d9a8836f5530755afab10e042c623f. Previously problematic code is now moved to win32u and doesn't use setupapi. Signed-off-by: Jacek Caban <jacek(a)codeweavers.com> --- dlls/user32/Makefile.in | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
