I will create two folders, lib with libihash.a and include with
ihash.h. What do you think?

Simplified.

ok, I will place a link with the discussion from bug hurd and explain
what it does.

I had to put one more line after AC_NO_EXECUTABLES, otherwise it would fail with

Other than that it works. I will confirm there.

It tries to link with a library in glibc (which at that point doesn't
yet exist ),
but it cant because of the AC_NO_EXECUTABLES flag saying that linking
is not allowed after this flag is passed. So I am just disabling the test, to
get the job done.

Thanks,
