Compilation fails with GCC 15: number of arguments doesn’t match prototype

[chusopr]

Compilation fails with upcoming version 15 of GCC with several errors about the number of arguments in the fuctions in src/utils/lib/md4_comp.c:

src/utils/lib/md4_comp.c: In function ‘MD4Init’:
src/utils/lib/md4_comp.c:76:6: warning: old-style function definition [-Wold-style-definition]
   76 | void MD4Init (context)
      |      ^~~~~~~
src/utils/lib/md4_comp.c:78:1: error: number of arguments doesn’t match prototype
   78 | {
      | ^
In file included from src/utils/lib/md4_comp.c:19:
src/utils/lib/md4.h:64:6: error: prototype declaration
   64 | void MD4Init PROTO_LIST ((MD4_CTX *));
      |      ^~~~~~~

That's the first one, but there are many more.

Full log attached.

The reason is that gcc15 dropped support for the old K&R syntax. I fixed this error in my fork with this patch: carlonluca/mldonkey@aa8787b. It cannot be applied to this repo, but the concept is the same.
