printing.zig uses pub extern "winspool.drv" and should be pub extern "winspool"

[LargoUsagi]

For example,

pub extern "winspool.drv" fn EnumPrintersA(
    Flags: u32,
    Name: ?PSTR,
    Level: u32,
    // TODO: what to do with BytesParamIndex 4?
    pPrinterEnum: ?*u8,
    cbBuf: u32,
    pcbNeeded: ?*u32,
    pcReturned: ?*u32,
) callconv(.winapi) BOOL;

should be

pub extern "winspool" fn EnumPrintersA(
    Flags: u32,
    Name: ?PSTR,
    Level: u32,
    // TODO: what to do with BytesParamIndex 4?
    pPrinterEnum: ?*u8,
    cbBuf: u32,
    pcbNeeded: ?*u32,
    pcReturned: ?*u32,
) callconv(.winapi) BOOL;

To leverage this part of the API I am now copying the extern and updating it like this.

extern "winspool" fn EnumPrintersA(
    Flags: u32,
    Name: ?win32.PSTR,
    Level: u32,
    // TODO: what to do with BytesParamIndex 4?
    pPrinterEnum: ?*u8,
    cbBuf: u32,
    pcbNeeded: ?*u32,
    pcReturned: ?*u32,
) callconv(.winapi) win32.BOOL;

It appears that dll's have their extensions properly trimmed but the drv file does not from the json generating code in this repository. https://github.com/marlersoft/win32jsongen
