did some testing... couldn't manage to get MS C compiler to generate similar debug info with PDB need a local variable, with a constant value; that constant value shall be generated depending on inlined function parameters; and reported in debug info as a constant at lowest optim level, MS C does keep variable, but doesn't report it as constant in debug info (just a regular local var), at highest optim, it's optimzed away but got clang to generate a constant local variable with bool type tested on windows with native dbghelp and I can confirm that the variant (describing the constant value) contains a signed integer so I raised https://gitlab.winehq.org/wine/wine/-/merge_requests/10621 to replace this MR -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10610#note_135802
