Re: cross gcc for pc windos x86 as host and powerpc as target

Hi Peter,

Thanks for the pointer. I could solve that problem.
It was picking one of my target include file causing this problem.

Now the make operation ends with following message !!!!!

cd ../libio ; make "SHELL=bash" "INSTALL=bash /cygdrive/e/gcc-2.95.2/install-sh

I checked config.log for the target directory there i see follwoing error
message
This config.log error is in /build-gcc/ppc-ibm-eabi/libchill & libobj,lib2fc

Am i missing some startup file here ?
I copied some target crt.o file to /usr/target/include directory.

Thanks
Sudhanshu

errno is not a variable, but a pointer to a function.  This is to
allow sperate threads having their own copy of errno.

Perhaps you could extract the command line used to compile fnmatch.c
and use the -E option instead of the -c option to get the output from
the preprocessor.  Then you can see how errno is being (incorrectly)
substituted.
