Bug in GUI App WinMain Arguements

I'm having a problem running a windows gui app with arguments from a mounted
directory if the Win32Path mounted to contains blanks. (i.e. mount -s -b
"C:/foo bar" "/foobar"). It's not a mount specific problem because it also
occurs if the directory has a space in it. Since mkpasswd defaulted my home
directory to "/cygdrive/c/Documents and Settings/cygusr", I am assuming
Cygwin supports directories with spaces in them. I have included a small
program that illustrates the bug.
By the way, I'm running on XP with the latest version of Cygwin newly
installed.
Also, according to the "Cygwin Users Guide", I have included the following
line in the code.
WinMainCRTStartup() { mainCRTStartup(); }
It doesnt seem to be called. Is the User Guide correct? The same problem
occurs if I omit the line and use the "-e _mainCRTStartup" as suggested in
the User Guide.
Any suggestions?

Assuming the program listed below (prtcmdline.exe) is in
"/cygdrive/c/Documents and Settings/cygusr"...
$ cd ~
$ pwd
/cygdrive/c/Documents and Settings/cygusr
$ ./prtcmdline arg1 arg2 | tail -
default
and Settings\cygusr\prtcmdline.exe" arg1 arg2 << wrong
$ cp prtcmdline.exe /home/cygusr
$ /home/cygusr/prtcmdline arg1 arg2 | tail -
default
arg1 arg2 <<right
$
/****************************************************/
/* prtcmdline.c */
/* gcc -mwindows prtcmdline.c -o prtcmdline.exe */

#include <windows.h>

char *gstr = "default\r";
WinMainCRTStartup()
{
gstr = "WinMainCRTStartup() called\r";
mainCRTStartup();
}
int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
puts(gstr);
puts(lpCmdLine);
return 0;
}
