    I had the same problem last week. It seems that mconf is linked 
using a .so file. I had to change this to link mconf with the .o file. I 
also had problems because to compile the kconfg_elk or something like 
that program in script/, we need elf.h header. I solve that using the 
libelf to have a elf.h under cygwin.
here is what i'm using:

gcc 3.2.3
glibc 2.3.2
binutils 2.14
kernel 2.6.7 (but the patch is also good for 2.6.6)

here is the patch i'm trying to use now, i'm still under progress for 
kernel 2.6.7 so i don't know if everything else will work:
