This is a result of a change yesterday which bumped the libgcc_s
version.  Obviously, the GCC build machinary doesn't set LD_LIBRARY_PATH
so that the newly built tools use the new version of libgcc_s.

This doesn't happen on the trunk.

The following from ada/Makefile.in is supposed to take care of that:

GCC_LINK="$(CC) -static-libgcc $(ADA_INCLUDES)"

(and uses of $(GCC_LINK) elsewhere in the tools).

Basically we certainly do *not* want to link with libgcc_s, in particular
to avoid this kind of nightmare.

This was fixed as part of:

        * Makefile.in: Link all gnat tools with -static-libgcc, since
        -shared-libgcc is now used by default on some systems (e.g. linux with
        recent binutils).

I am surprised that there's a regression between 4.1 and trunk here.

A work around is to export an appropriate LD_LIBRARY_PATH in the build
script, or add it to the environment variables passed to make.

For some reason, the above doesn't seem to have been used in linking gnatmake:

../../xgcc -B../../ -DIN_GCC   `echo -g -O2 -W -Wall -Wwrite-strings

Possibly, this is the reason:

../../gnatmake$(exeext): $(P) b_gnatm.o link.o $(GNATMAKE_OBJS)
        $(CC) $(ALL_CFLAGS) $(LDFLAGS) -o $@ b_gnatm.o $(GNATMAKE_OBJS) \

Indeed, gnatmake has to be handled specially.

So I guess the gnatmake rule needs to use $(GCC_LINK)
one way or another (although there should be no difference between
trubk and 4.1 in that respect).

Same for gnatlink.

In the trunk, I see the following in the build log:

 export GMPINC; LD_LIBRARY_PATH=`echo
"$r/hppa-linux/libstdc++-v3/.libs:$r/hppa-linux/libmudflap/.libs:$r/hppa-linux/libssp/.libs:$r/./gcc:$r/./prev-gcc:$LD_LIBRARY_PATH"
| sed 's,::*,:,g;s,^:*,,;s,:*$,,'`; export LD_LIBRARY_PATH;
LD_LIBRARY_PATH=`echo "$LD_LIBRARY_PATH" | sed 's,::*,:,g;s,^:*,,;s,:*$,,'`;
export LD_LIBRARY_PATH; \
         echo Configuring stage 1 in ./gcc ; \

It's not possible to use $(GCC_LINK) directly because of the quotes
in the define of GCC_LINK.  It might be best to remove them and modify
each use as necessary.  However, the following change is less invasive
and fixes the problem.

Thoughts.
