Linker error when improving GetLargestConsoleWindowSize

I've written a function to determine the largest possible screen buffer that wineconsole is able to display. This function replaces the hard-coded constants listed in both instances of GetLargestConsoleWindowSize in dlls/kernel32/console.c.

#include <windows.h>
#include <winuser.h>


COORD GetLargestConsoleWindowSize_helper(HANDLE hConsoleOutput)
    RECT workarea;
    COORD console_fontsize;
    COORD max_console;

    SystemParametersInfoA(SPI_GETWORKAREA, 0, &workarea, 0);
    console_fontsize = GetConsoleFontSize(hConsoleOutput, 0);

    max_console.X = (workarea.right / console_fontsize.X) - 6;
    max_console.Y = (workarea.bottom / console_fontsize.Y) - 6;

    return max_console;

While dlls/kernel32/console.c compiles, I'm having trouble with the final compile-time linking.  It seems that SystemParametersInfoA is an undefined reference, but windows.h and winuser.h are included in console.c.  This is the terminal output:

/usr/bin/ld: final link failed: Bad value
collect2: error: ld returned 1 exit status

Unfortunately, my knowledge of C is terrible, so I'm not sure what to do from here.  If someone could help me solve this, I'd appreciate it.

If it helps, I'm able to use winegcc to build a simple Windows executable using SystemParametersInfo without any problems.

Thank you in advance,
