Website page states "cvs co -c" ?; gcc in NT croaks using Cygwin winnt.h





I hope you update your CVS pages so that they say how to list
the modules. It seems to be a most obvious thing to document but
most people would find that information very difficult to find.

Please document   'cvs co -c' at the gcc website.
Maybe this is the best page for such a comment:

http://gcc.gnu.org/cvs.html

Or every page including, e.g., the page saying how to get GCC Java via cvs.

Here is a log showing that 'cvs co -c' does list the special options.
That allows people to see all the options before they start and thus
it could improve their opinion of your cvs service, as well as allowing
lower running costs.

I found that "cvs co -c" was mentioned at this Usenet webpage:
http://groups.google.com/groups?hl=en&threadm=fa.e59sr3v.17h41om%40ifi.uio.no&rnum=1&prev=/groups%3Fq%3Dcvs%2B%2522list%2Bthe%2Bmodules%2522%26num%3D100%26hl%3Den%26scoring%3Dd

Can the pages be updated to show that "cvs co -c" allows smaller downloads.
That lists "ada" as being part of GCC. The online documentation says all this
which is plainly incomplete and it does not mention Java or FORTRAN and it
does not say that "cvs -z9 co gcc-ada" can entered.

This is the last console log I got from a compile of GCC. I tried using
some old cygwin header files and that did not fix the problem. Possibly
it got fixed.

The whole compile process depends on files that are not provided by gcc.
The winnt.h file that causes gcc to be unable bootstrap and build itself
is provided by Redhat or Cygwin. I presume the problem is a gcc bug.

I just re-cvsupped and it looks like the GCC file that was causing the
bootstrap compile of GCC to crash, has not been updated.
I am not really concerned by it but I was wondering if it might compile
in 2002. It looks like it didn't compile in Windows NT in 2001. It seems
to have been taken down by Redhat include files, yet I guess it has been
a problem with gcc code having bugs. The seemingly offending part of
winnt.h was last changed in the approx February 2001 release or so.
So I guess it did not run since then. Gcc also would not compile when
older Cygwin headers were used.

I was using these options.

   $ nice ../gcc/configure --enable-libgcj --enable-threads=posix \
     --prefix=/gccj --enable-shared --enable-languages=c++,java \
     --with-as=/bin/as --with-ld=/bin/ld

   $ nice make bootstrap
   $ nice make
   $ make install

It was dying on the 'make bootstrap' or on the 'make'

I once wrote to a Redhat developer in Brazil who said when gcc does
not compile then it does not compile. It seems to be noncompilable
because of Redhat code and it has been bootstrappable for most of
2001.

Hopefully Gcc would move over to Ada which runs well and has
better error messages.

I suppose the person reading this might not be able to do much about
GCC "won't compile - bugs" problems.



////////////////////////////

The Internet Explorer 5.5SP2 tells the webserver of the GCC CVS website
to gzip the data. Then when MSIE gets the gzipped data, it can't decode
it. Accepting that as my problem, I not that another way to reduce
bandwidth is to document  "cvs co -c" and say that it lists modules.
