Ignoring the cross stuff, if this is all you need I would suggest calling
make in the right way to generate this script. We'll use a fake
"compiler" for making cc1 which does nothing else than appending its
command line to your compile script. Hence, create a script
collect-stuff.sh with this content:
-------- snip ----------
#!/bin/sh
echo stdcomp ${1+"$@"} >> /tmp/compile
-------- snap ----------
Now we'll call make so that it only tries to make cc1 with this compiler
to collect the commands:
% cd gcc
% make CC=collect-stuff.sh cc1
/tmp/compile will now fill up with the commands to use. If you don't need
the various options, also add "ALL_COMPILERFLAGS= ALL_CPPFLAGS=" to the
make command (might be other variable names in the old 4.x compilers), or
amend the collect-stuff.sh script to not echo them.
Remember to clean the build dir before doing this as otherwise some .o
files aren't remade.
Ciao,
Michael.
