Bug ID: 50429
           Summary: Serious Sam Engine / Serious Sam Classic broken MP
                    with math functions from musl
           Product: Wine
           Version: 5.15
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: msvcrt
          Assignee: [e-mail]

The problem described in #10229 reappears with version 5.15 of wine:

Cross-Platform Network Multiplayer with Serious Sam Classic (First or Second
Encounter) is not possible. After some time all clients, which run on a
different platform, desync.

I suspect the commit 8034d4179c88ae9176ecaae210c30e40084ae29c is responsible.
To test this, it is best to start a dedicated server on a windows machine with
the "DemoCoop" profile of The First Encounter and then try to connect from
Serious Sam started under wine.
The connection fails instantly with "CRC error in DIFF!".

Tested with 784cb2060ab63076adc349dcb1d15a6cb5eb2bc4 (master) on Arch Linux
x86-64.

If using version 5.14 everything works as expected.
