[Qemu-devel] Configure doesn't honour CC variable

[Qemu-devel] Configure doesn't honour CC variable

When running "configure" I get

'ERROR: "gcc" looks like gcc 4.x'

even though I've set the CC environment variable to point to my copy of
gcc version 3.2.2

Qemu's configure is not like most other configure scripts.

You have to use the --cc="$CC" command line option to Qemu's configure,
to get it to use a different compiler.

You might need to use the --host-cc="$CC" option as well.

Nope, that didn't work:

[njh@njh qemu]$ ./configure --cc=/home/njh/build_3.2.2_dir/gcc/xgcc
ERROR: "/home/njh/build_3.2.2_dir/gcc/xgcc" either does not exist or 
does not work
[njh@njh qemu]$ ls -l /home/njh/build_3.2.2_dir/gcc/xgcc
-rwxrwxr-x 1 njh njh 85636 Aug 28  2005 /home/njh/build_3.2.2_dir/gcc/xgcc
[njh@njh qemu]$ ./configure --cc=/home/njh/build_3.2.2_dir/gcc/xgcc 
--host-cc=/home/njh/build_3.2.2_dir/gcc/xgcc
ERROR: "/home/njh/build_3.2.2_dir/gcc/xgcc" either does not exist or 
does not work

And before your say, yes, I am sure that my 3.2.2 build works.
