[Bug bootstrap/18547] New: Cygwin

In latest change in cygwin 1.5.12-1, all volumes default binmode. In Win32 
configurations using cygwin: genconditions.exe creates insn-*.c files that 
contain 0xD, which causes "make bootstrap" to fail. Isolated to gensupport.c 
init_md_reader. Fix is as follows:
Line 920 currently reads:
     input_file = fopen (filename, "r");
Line 920 should read:
     input_file = fopen (filename, "rt")
This fixes reading condition files in text mode vice default (binary mode). In 
binary mode for win32, 0xD will be read in. In text mode for win32, 0xD is 
suppressed. (Win32 systems store 0xD before 0xA ('\n') for text files)
Note that this bug will not affect non-win32 systems as for most other systems 
text mode = binary mode.

Text mode is the default at least according to C89 so the bug is in cygwin and not GCC.

If you want a file to be mode 'A' then read/write it in this mode explicitly.
You cannot expect the underlying OS to know who is reading/writing a file and
how to do it without explicitly telling the OS what is expected.

But since the C standard says it is in text mode by default, it is the underlaying OS to do that and not to 
mess up.  Also the C standard says to enable binary mode by using the b mode.
