I used to build colinux on Debian. It works fine until recently I am building colinux on Fedora 11/CentOS 5.3. The configure test couldn't pass. Because the test for binutil reports a wrong version number.
The "as --version" outputs "GNU assembler version 22.214.171.124.14-1.fc11 20090722".
So the configure matched 1.0.14 (Checking as binutils for kernel ... (1.0.14) wrong version).
I fix the configure by changing the wildchar ".*" to non-number "[^0-9]*".
And the patch is attached.
