[net release] solution to -mno-cygwin problem

[net release] solution to -mno-cygwin problem

[Mumit Khan]

Thanks to a lovely cold, and I'm home with time to install the new net
release, and of course the first thing I tried was to reproduce the 
-mno-cygwin problem reported lately.

Here's the symptom: when you -mno-cygwin, gcc should be looking in mingw
include directory first, but it's not.

The problem: We somehoe mixed up the name mingw and mingw32, and things
have gotten confused. GCC is looking for a directory named:
  
  /usr/i686-pc-cygwin/include/mingw32

whereas the directory is named:

  /usr/i686-pc-cygwin/include/mingw

in the net release. Something that will fixed soon.

The solution is any one of the following three:

1. Symbolically link the following:
   
   $ cd /usr/i686-pc-cygwin/include
   $ ln -s mingw mingw32

This is what I've done locally.

2. Rename the directory:

   $ cd /usr/i686-pc-cygwin/include
   $ mv mingw mingw32

Just as easy.

3. Edit the gcc specs file (`gcc -print-file-name=specs'), taking care
   not to wrap any lines and so on, and change `mingw32' to `mingw' in
   the:
     -iwithprefix ../../../../include/mingw32 
   to
     -iwithprefix ../../../../include/mingw

Regards,
Mumit

Where is _what_ documented?

You can get a list of options via `gcc -v --help > gcc.help 2>&1'.  You can
also look at the info file documentation.

As for the specs file itself, I've been told that the documentation resides in
the gcc source code.

 OK. Where is this documented? I once thought I
needed to edit the specs file and didn't have a
clue. (Yes, I know this can be dangerous.)

       -iwithprefixbefore

FTR, the difference is -iwithprefix puts the directory _after_ the list of
already included directories and -iwithprefixbefore puts the directory _before_
the list of already included directories.

It's just one person who claims to be a user not a programmer that thinks he
knows more than he does.  He's trying to get something for nothing by bad
mouthing and complaining.  The verbage gets rather long.  Best just left
ignored.

???  I guess I have to start reading this mailing list.  I can't imagine
how any sane person could criticize Mumit for his manifold and amazing
contributions to free software.

Which do you prefer?  It looks like "make install" in the mingw directory
defaults to "mingw".  I think we should probably stick with the mingw32,
though, if that's what we've always done.

That means renaming the directory in the tar file and changing configure.in
in winsup/mingw.

Agreed?

 I hope you aren't referring to the completely
unwarranted recent attacks on the mingw mailing
list.  In any case, please get well soon.

I'm having trouble typing this note, and looks like my body is fighting
back for the all abuses of late. I'd very much appreciate it if you could
take care of it (any of the 3 solutions will work of course).

I Should've paid more attention after the cygwin source re-arrangement.
Oh well. The screwup can be fixed either:

1. Change winsup/mingw/configure.in HEADER_SUBDIR to mingw32 instead
   of mingw.

2. Chagne the gcc specs file of course.

Mumit
