i386-elf/coff cross build

[Alagu Sankar]

Hi all,
 
I am in the process of building cross compiler 
tools for intel 386 embedded target with a custom RTOS.  Has anybody 
succeded in installing the i[3456]-elf or i[3456]-coff gcc cross compilers with 
linux or windows(cygwin) host. I'm seeing lot of failure stories in building 
i386 cross tools in the mailing list
 
I am using gcc-2.95.2 with newlib-1.8.2.  I am 
able to build bin utils for i386-coff successfully. But when i try to install 
gcc i am getting the follwoing errors ( I tried 
with both cygwin and linux host but the result is same).  Any 
help in solving the problem is very much appreciated.

I was successfull in creating powerpc-eabi and 
arm-coff for both the host and obviously i follow the same procedure for 
building i386-coff also.
 
I have got one more question. Does anybody know, 
like.. what are the issues in using gcc with a custom developed RTOS 
(not RTEMS or eCos) and its own C library routines for am embedded 
target.
 
Thanx in anticipation
