Attaching the s-osinte-gnu.ads file for review as promised. Will
continue hunting the task executable bug(s).
Regarding gnat-4.6 and gcc-4.6 on debian-ports. Can you remove the
following patches from gcc-4.6.3 (and gcc-4.7.0):
ada-bug564232_new.diff (the updated one, replaces the old patch)
ada-libgnatprj_new.diff (the updated one, replaces the old patch)
gcc_ada_gcc-interface_Makefile.in.diff
s-osinte-gnu.diff
s-taprop-gnu.diff
And add them to the gnat-4.6 source, mainly containing the Ada-specific
patches): gnat-4.6_4.6.3-x.tar.gz
The following (attached) patch should be added to gnat-4.6:
debian_rules.patch.diff
The only patch to be added to gcc-4.6.3 and 4.7.0 is the attached
debian_rules.def_ada.diff. I would like to add bug reports for this
patch now, since they only concern the compiler driver gcc-4.x.
Since the gnat distribution mainly consists of patches to the gcc-4.6
(gcc-4.7) tree, the patches should be applied to the gnat-4.6 tree, not
gcc-4.6 (or gcc-4.7). Having them in gcc complicates a lot since gnat is
built using the gcc tar file linked to the gnat-4.6 directory.
Thanks!
