  That's strange.  I don't have any problem with gencodes; but one mystery
I've never been able to understand is that my fixincluded headers get
dos style line ends even when I've stripped all the originals (in 
$prefix/sys-include) and my build dir is mounted unix mode and my source
dir is mounted text mode.  In particular, I've never had any trouble
with the .md or other config files, except when I've forgotten to use
the textmode path to invoke the toplevel configure command.  I haven't
investigated or experimented, but I've wondered if it somehow relates to
the mode of the /tmp dir, which an awful lot of files pass through on
their way from one place to another.

  Hmm.  A second thought occurs to me: you aren't using winzip to untar
the source, are you?

Hi David,

I didn't have a problem with 2.95.2, but sometime in more recent versions 
this behavior has become broken on cygwin.

The instructions Red Hat provides for building the ARM tools (as part of 
the eCos install process) specifically say that /tmp should be mounted in 
binmode. Normally /tmp is just an inheritor of the (binmode) / mount point, 
so this is the default behavior.

No, these sources were obtained directly using cvs. It's all very mysterious.

I am already doing this (it's impossible to build without doing this), but 
it doesn't fix all these problems (for instance, gencodes.exe needs the 
source file to be UNIX-format, even if the file is on a text-mode mount 
point). I _HATE_ the whole issue of text-mode.

  I'm not working on 3.0 or arm so I can't help you much, but I would
like to offer one little time-saving tip: make a cygwin mountpoint in
text mode for the top-level gcc directory in your source tree and use
that path to the configure command (which then gets adopted as the 
--srcdir setting).  Much easier!

Still problems with latest CVS for arm-elf (cygwin)

[Lewin A.R.W. Edwards]

I'm working with the latest (this morning) CVS and it has fixed the link 
error to PUSH_ROUNDING. However even after considerable massaging, I have 
hit a compile problem I just can't solve.

(Note that the line numbers in longlong.h mentioned below don't exist).

I'd love some more help on this...

The text below assumes you have your gcc sources in /src/gcc/gcc-xxxxxxxx 
and your temp build directory is /tmp/build/gcc.

Strip CRs from /src/gcc/gcc-xxxxxxxx/gcc/config/arm/arm.md
Build according to instructions. You'll eventually get to about 10,000 
lines of errors. Strip CRs from /tmp/build/gcc/gcc/tconfig.h and edit that 
file:
add to the top:
#ifndef LARWE_TCONFIG_H
#define LARWE_TCONFIG_H
add to the bottom:
#endif
Strip CRs from the file /src/gcc/gcc-xxxxxxxx/gcc/config/arm/elf.h, edit 
the file and add to the top:
#ifndef LARWE_ARM_ELF_H
#define LARWE_ARM_ELF_H
add to the bottom:
#endif
Strip CRs from the file /src/gcc/gcc-xxxxxxxx/gcc/config/arm/unknown-elf.h, 
edit the file and add to the top:
#ifndef LARWE_UNKNOWN_ELF_H
#define LARWE_UNKNOWN_ELF_H
add to the bottom:
#endif
Strip CRs from the file /src/gcc/gcc-xxxxxxxx/gcc/longlong.h, edit the file 
and add a blank line to the end.

Now you wind up with these errors:
