Running make check stops in the Ada ACATS part,
where it doesn't find the newly created binaries
after a successful make bootstrap. (And after turning
the computer off, going to sleep, turning it on and
*not* again adding the different GNAT installation to
PATH that was used for bootstrapping.)
I think this is caused by where variables are set in
run_acats, as outlined below.
(Or has some PATH setting gone from the Makefiles?)
Effects of $ make check[-ada] are these:
$ make check
...

$
This happens when running either $ make check from the top
level build directory, or $make check-ada from the gcc
directory below the top level.
The shell script .../run_acats sets two variables,
host_gnatchop=`type gnatchop | awk '{print $3}'`
host_gnatmake=`type gnatmake | awk '{print $3}'`
However, the programs gnatchop and gnatmake cannot
be not found in $PATH yet because only later the script
modifies PATH to include the new binaries.
(Or else, the gnatchop and gnatmake programs
will be from a different installation, if some full GNAT
is still in $PATH ...)
The script goes on to create two more scripts in the testsuite
directories: host_gnatchop and host_gnatmake. It's using echo
like this:
echo PATH=`dirname $host_gnatmake`:'$PATH' >> host_gnatmake
But $host_gnatmake is empty here, as per the above! Therefore,
echo export PATH >> host_gnatmake
echo exec $host_gnatmake '"$@"' >> host_gnatmake
will result in the quoted error messages when run. Exec will only
have an option (-q) to execute, so to speak.
I thought a solution could then be to add the new GCC's GNAT binaries
directory to $PATH before run_acats employs "type" to find them.
However, this does not work. One effect is that system.ads is not
found. I have the script print out the new settings:
ROOT: /werkstatt/georg/build/gcc/testsuite/ada/acats
PATH: /werkstatt/georg/build/gcc:\
/werkstatt/georg/build/gcc/testsuite/ada/acats:\
/usr/local/bin: etc as usual, no other gnatmake

The system.ads is right there I think,

What's going on? Am I doing anything wrong?
