Need sources for libc

[Shimon at Centillium.com (Simon Edelhaus)]

We are using RTEMS 4.6.0-prel3 for MIPS 4KC. Tools and libc version:
  
  	Reading specs from /opt/rtems/lib/gcc-lib/mips-rtems/3.2.1/specs
  	Configured with: ../gcc-3.2.1/configure  
 --build=i686-pc-linux-gnu --host=i686-pc-linux-gnu 
  --target=mips-rtems --	with-gnu-as --with-gnu-ld 
  --with-newlib --verbose --with-system-zlib --disable-nls 
  --enable-version-specific-	runtime-libs 
  --enable-threads=rtems --prefix=/opt/rtems 
  --enable-languages=c,c++,ada Thread model: rtems gcc version 	
  3.2.1 (OAR Corporation gcc-3.2.1-20021209/newlib-1.11.0-20030203 2)
  
  	From inside libc.a :
  	+++++++++++++++++++++
  	../../gcc-3.2.1/newlib/libc/stdlib/strtod.c^
  	@/home/rtems/src/packages/BUILD/mips-rtems-gcc 
   -newlib/build/mips-rtems/newlib/libc/stdlib/	
   ^@../../../../../gcc-3.2.1/newlib
  	/libc/stdlib/strtod.c^@gcc2_compiled
  
   We have a nasty crash in our application. We get:
  
  	assertion "0" failed: file "../../../.
  
  Unfortunately CPU dies before we get a chance to see the 
  file  and line number.
  We think this assertion printout is coming from the "libc.a". 
  We only have the object. 
  
  Where do we get the sources for this, to modify the string 
  to  be much shorter to get the file and line number printout 
  for  above assertion? And how do we rebuild "libc.a" correctly?
  
  Thanks in advance for any help.
  
  Thank you very much!
