RE: Problem compiling cygwin1.dll from CVS

You are right, the problem I am referring to is the parse error in line 4 of
In fact, I even think that this very parse error is nothing but a side
effect of the previous step failing (the generation of Cygwin0.dll, as you
will see in the attached log).

Here's what I did to re-build Cygwin:
Download the sources via CVS and place them in /Cygwin/src
Create a dir /Cygwin/obj where to build Cygwin, and a dir /Cygwin/install
where to install it.
I then moved into /Cygwin/obj and launched to following command lines:
../src/configure --prefix=/Cygwin/install -v > configure.log 2>&1
make > make.log 2>&1
And this is where is fails...

The log files are attached to this mail, along with the result of
cygcheck -svr.

The last line of my make.log are the following:

As you can see, there is a segmentation fault in the c++ -o cygwin0.dll
command and I think this is where the problem lies.

Thanks for your help...

By "exactly the same build problem" I assume you mean a parse error in
line 4 of cygwin.def?  Could you please attach (*not* include inline) your
generated cygwin.def, the output of "cygcheck -svr" on your system, the
exact flags you're passing to "configure", and the exact command that
