I have also seen similar faulure, and the reason on my environment is as 
follows.

(1) In my case, gcc build complete successfully.  But a.exe which is 
compiled from the new compiler fails. Error message is

$ ./a.exe
bash: ./a.exe: Permission denied

Source code of a.exe is quite simple:
main()
{
   printf("Hello\n");
}

(2) This failuer occurres from gcc trunk r148408.  r148407 is OK.

(3) r148408 removed "#ifdef DEBUG_PUBTYPES_SECTION".  r148407 does not 
generate debug_pubtypes section, but r148408 and later version generates 
  debug_pubtypes section in object when we set debug option.

(4) gcc build sequence usually uses debug option.

(5) My cygwin environment seems not to accept debug_pubtypes section, 
and pop up "Permission denied" error.

When I reverted "#ifdef DEBUG_PUBTYPES_SECTION" in dearf2out.c, the 
failuer disappeared.

Does this failure occurr only on cygwin?
