Hi,
there appears to be a bug in WITHSYSROOT and TARGET_SYSTEM_ROOT handling.
WITHSYSROOT is always set, even if --with-sysroot is not given. The
reason is that configure.ac sets with_sysroot to yes by default.
This should be changed, IMHO, since sysroot only makes sense if
sysroot is not / anyway.
However, even if that's not changed, TARGET_SYSTEM_ROOT is set to
with_sysroot, which is set to $prefix/include by default. That's kind
of weird. Makefile.am sets sysinclude to -I@TARGET_SYSTEM_ROOT@/include,
which means, the resulting path is =I${prefix}/include/include. I assume
that's not supposed to be...
Patch suggestion below.
Corinna
* configure.ac (sysroot): Default to no sysroot. Set sysroot to
$prefix since include is attahed in Makefile.am anyway.
