Crosstool 0.28 failure building mipsel on cygwin

[Joel Sumner <joel dot sumner at ni dot com>]

First of all, thanks to all of the folks who are trying to make building 
a gcc cross compiler easier. I told my coworkers that I was looking into 
building a gcc cross compiler and I got looks of amusement mixed with 
horror.  I've spent the last few days wrestling with old and obsolete 
instructions:

http://www.onkelinx.com/agenda/compiling_toolchain.html
http://www.village.org/villagers/imp/build.html
http://www.student.cs.uwaterloo.ca/~cs350/common/make-linux-gcc.html

or ones that have never been looked at on cygwin

http://openwrt.org/userguide.html
http://www.singingtree.com/~mikey/linksys-firmware.html
http://cmeerw.org/dev/node/125
http://openwrt.org/forum/viewtopic.php?t=15&highlight=build

So imagine my surprise to find crosstool actively supporting cygwin and 
also having the exact build configuration I was looking for (demo-mipsel.sh)

So, I'm hoping that after a few days of wrestling with the build 
process, I'm nearing success.  I've run into a problem that I don't know 
how to deal with however:

I'm running Windows XP SP2 and an install of cygwin that defaulted to 
just about everything.  The cygwin packages were last updated 
yesterday.  I've got crosstool untarred in

/cygdrive/c/linksys/crosstool-0.28-rc37
I changed demo-mipsel.sh to change the tarball directory to 
$PWD/downloads and I'm building the configuration

"eval `cat mipsel.dat gcc-3.2.3-glibc-2.2.3.dat`        sh all.sh --notest"

This configuration is mentioned in demo-mipsel.sh as working with the 
Linksys WRT54G router and that configuration is also mentioned as being 
good at http://kegel.com/crosstool/#results.  However, it's failing in a 
way that's very similar to the failures mentioned on the crosstool build 
logs page, specifically the

gcc-3.3.4,glibc-2.2.5,binutils-2.15,linux-2.6.8 Failure at 
http://kegel.com/crosstool/crosstool-0.28-rc37/buildlogs/0.28/mipsel-gcc-3.3.4-glibc-2.2.5.log.txt
and the
gcc-3.4.2,glibc-2.2.5,binutils-2.15,linux-2.6.8 Failure at 
http://kegel.com/crosstool/crosstool-0.28-rc37/buildlogs/0.28/mipsel-gcc-3.4.2-glibc-2.2.5.log.txt

Here are the first few relevant lines of the output log:

...........

It made it through building binutils and gcc but it falls over a ways 
through building glibc

I am also somewhat suspicious of the following errors while making the 
dependencies but crosstool kept going so I assumed they were ok.

I got a bunch of them...

I'm going to go try build  gcc-3.3.4, glibc-2.3.2, binutils-2.15, 
linux-2.6.8 since that is listed as working right now on the buildlogs 
page to see if I can get that one to work.

Is there something not set up properly on my machine? 

Thanks
