failing to build gnatcoll on linux

[Joel Reymont]

Any suggestions on why this is happening? I have gnat-4.4 and gprbuild installed.

    Thanks, Joel

Same symptoms as http://bugs.debian.org/633981; feel free to subscribe
to that bug if you want to be notified of any changes.

Apparently this is an unwelcome consequence of the ongoing transition to
multiarch support.  This bug does not affect Debian 6 "Squeeze" though;
only "testing" and "unstable".  It would be nice if Stephe could provide
a workaround, perhaps by patching the database of compilers known to
gprbuild?

Fixing gprbuild to use the multiarch paths is not hard; I'm currently
waiting on gnat 4.6 being promoted to the default compiler; I think
that's the gateway to uploading new versions of any Ada package.
