Hello Niels,
first of all, the program_invocation_name problem was indeed a bug in
uClibc. glibc sucks the variable in from libc.map, whereas uClibc doesn't
have support for program_invocation_name. The declaration in errno.h came
from the original glibc errno.h. In the current CVS this was removed by
the maintainer.

Indeed, very strange.

I'll test this again tomorrow, because I have to downgrade uClibc to the
version from yesterday.
Attached you'll find my patch which lets you compile lsh-1.2.5 with both,
glibc and uClibc. With glibc there is still the problem with addprefix,
but if I remember correctly you had already found a solution for that.
Hope that helps, and thanks for your patience!
Robert
