            Bug ID: 59211
           Summary: Too long argument list may cause build failure.
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Windows
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: tools
          Assignee: [e-mail]
          Reporter: [e-mail]

The `spawn` in `tools\winebuild\utils.c` may generate a very long argument list
to system. It will be failed on Windows.

```c
void spawn( struct strarray args )
{
    int status;
    const char *argv0 = find_binary( NULL, args.str[0] );

    if (argv0) args.str[0] = argv0;
    if (verbose) strarray_trace( args );

    if ((status = strarray_spawn( args ))) /* <-- Argument list too long (e.g.
1234 arguments) */
    {
    if (status > 0) fatal_error( "%s failed with status %u\n", args.str[0],
status );
    else fatal_perror( "winebuild" );
    exit( 1 );
    }
}
```

GNU ar supports `@file` to provide arguments. I think it's a better idea.
