ExitProcess does not work in Cygwin?

$ rm *.exe

# u is for Unix
# w is for Windows

$ cat u.c
#include <stdlib.h>
int main()
{
 exit(1);
}

$ gcc u.c
$ ./a.exe

$ echo $?
1

 => as expected

$ cat w.c
#include <windows.h>

int main()
{
 ExitProcess(1);
}

$ gcc w.c
$ ./a.exe

$ echo $?
0

 => not expected

$ uname -a
CYGWIN_NT-10.0 jayk-tp4 3.3.3(0.341/5/3) 2021-12-03 16:35 x86_64 Cygwin

works in debugger:

$ /cygdrive/c/bin/amd64/windbg.exe .\\a.exe

$ echo $?
1

?
