I think it is 20 -- use WinQueryQueueInfo() to check.

Not by much.

Note: fixpak 16/17 raise the default msg queue size to something like 2000.

There is also a freeware program called something like PMQSIZE.ZIP which
will increase it for 2.1/Warp -- I used it all the time until a few days
ago when I installed fixpak 17.

This program displays 3000 on my pc:

 icc /Rn /Kb /W3 /SS /B"/pm:pm" /Ti small2.c
 #define INCL_WIN
 #include 
 #include 

 #define ID_WINDOW 1

 int main(void)
 {
     HAB hab;
     HWND hwndClient;
     ULONG flCreate;
     QMSG qmsg;
     char msg[100];
     MQINFO mqinfo;

     hab = WinInitialize(0);
     WinCreateMsgQueue(hab, 0);

     flCreate = FCF_SHELLPOSITION | FCF_SIZEBORDER | FCF_TASKLIST |
                FCF_SYSMENU | FCF_TITLEBAR;

     WinCreateStdWindow(HWND_DESKTOP, WS_VISIBLE, &flCreate,
         WC_STATIC, "Title",
         SS_TEXT | DT_CENTER | DT_VCENTER,
         0, ID_WINDOW, &hwndClient);

     mqinfo.cb = sizeof(mqinfo);
     WinQueryQueueInfo(HMQ_CURRENT, &mqinfo, sizeof(mqinfo));
     sprintf(msg, "Queue size = %d", mqinfo.cmsgs);

     WinSetWindowText(hwndClient, msg);

     while (WinGetMsg(hab, &qmsg, 0L, 0, 0))
         WinDispatchMsg(hab, &qmsg);

     return 0;
 }
