What version of linux-wlan-ng recommended for 2.4.X?

Hey folks,

I've been using 0.1.16-pre4 with a PCI-only Prism card on a 2.4.18 
kernel for several years. I just updated the kernel to 2.4.31, and 
although 0.1.16-pre4 builds and works fine on the new kernel, I thought 
that I'd see what the latest linux-wlan-ng was. I snagged a copy of the 
0.2.1-pre26 and tried to build it but got the following error during 
'make all':

Any suggestions? Is 2.4.X support deprecated?

Thanks,
