I also up to recently used similar directory layout for building GCC for
target i586-pc-msdosdjgpp (build directory was subdirectory of source one
and I run configure using relative path). With GCC-3.2 I found that
I'm getting trouble with 'make -C gcc gnatlib_and_tools'. Moving build
directory out of source one fixed problem and I'm using relative path to
configure (like ../gcc-3.2/configure ....).
So my experience shows that simple moving build directory from
build.djg to ../build.gcc relative to source directory fixed build failure
with building gnatlib and Ada tools. I didn't study this problem more
detailed though. I remember trying something similar under Linux and
getting the same problem, but I may be wrong.
This was really only problem with build directory being subdirectory of
source directory I have noticed up to this time.
