Thank you so much!!!!
I didn't think of using 2.4 headers... bad me!
Anyway, I can now hack this to compile with uclibc...
I don't know if it works yet, but at least it builds now (26KB)
I had to use newer kernel, as I had some gcc related errors in include/asm/processor.h
and CONFIG_SMP related conflicts.
I truly hope maintainer will find some time to make it regular 2.6.X user mode
application... There are many packages that use kernel headers, but are much
easier to build, without sharing one object between kernel and userspace.

So just for the record...
I am using the following script to build:
ldm=linux-ldm-0.0.8
kernel=linux-2.4.35.4
wget --continue http://downloads.sourceforge.net/linux-ntfs/$ldm.tar.bz2
wget --continue http://www.kernel.org/pub/linux/kernel/v2.4/$kernel.tar.bz2
tar xjf $ldm.tar.bz2
cd $ldm
patch -p1 < ../$ldm-build.diff
tar xjf ../$kernel.tar.bz2
yes n | make -C $kernel ARCH=i386 oldconfig dep
make clean
make KERNEL=$(pwd)/$kernel LDMINFO_LDFLAGS=-static
#make KERNEL=$(pwd)/$kernel LDMINFO_CC=i586-pc-linux-uclibc-gcc
And the following patch:
