Attempting to bootstrap gcc-10.1.0-RC-20200430 with Ada on Cygwin64
fails with several errors.
The first is:

mingw32.h has this at line 60:
/* Note: windows.h on cygwin-64 includes x86intrin.h which uses malloc.
That fails to compile, if malloc is poisoned, i.e. if !IN_RTS. */
#define _X86INTRIN_H_INCLUDED
#endif
#include <windows.h>
<windows.h> now also drags in <emmintrin.h>, so the fix is to add:
#define _EMMINTRIN_H_INCLUDED
The second error is:

which is another occurrence of the previous issue. Here we need to add:
#define _X86INTRIN_H_INCLUDED
#define _EMMINTRIN_H_INCLUDED
before including <windows.h> in unwind-generic.h. Both are needed, as
defining either one isn't enough to prevent all errors.
The third error is:

which is because g-sercom.ads changed the Serial_Port_Descriptor type, but
g-sercom__mingw.adb missed an adjustment; here the fix is to wrap the code
in call to Serial_Port_Descriptor ().
With those three fixes bootstrap is successful.
Patch is being prepared.
