--- Comment #2 from Martin Storsjö martin@martin.st --- This is a bug with how Wine has integrated the musl sources.
Musl removes excess precision from float values in a number of places, this seems to be critical to get the intended precision, see https://gitlab.winehq.org/wine/wine/-/blob/wine-9.3/libs/musl/src/internal/l....
However, in order for this to work as expected, musl also tries to add specific compiler flags, in order to get the right behaviour. See https://git.musl-libc.org/cgit/musl/tree/configure?h=v1.2.4&id=f5f55d658... - which does this:
tryflag CFLAGS_C99FSE -fexcess-precision=standard \ || { test "$ARCH" = i386 && tryflag CFLAGS_C99FSE -ffloat-store ; }
So wine would need to check for these flags somewhere, and enable them for the musl sources.
