Comment (by RyanGlScott):

 The issue stems from the order in which `ntdll` and `msvcrt` are given to
 the linker when compiling the executable. If you compile with `-v3`,
 you'll discover this linker invocation:

 {{{
 "gcc.exe" ... "-lntdll" ... "-lmsvcrt" ...
 }}}

 If you swap the order in which `msvcrt` and `ntdll` are linked:

 {{{
 "gcc.exe" ... "-lmsvcrt" ... "-lntdll" ...
 }}}

 Then it works.
