On host: i686-pc-linux-gnu (Redhat 7.1 installation style), where original 
software exists in: /usr/bin... & /usr/lib...

Using gnat-3.13p-8 (complete, rpm, binary, install) from www.gnuada.org
which also installs in /usr/bin & /usr/lib...

Ensuring that /usr/bin is first entry in $PATH and specifying: 
export CC=/usr/bin/gnatgcc
Almost works...  If (or when) bootstrap exits with an "ensure you are using a 
compatiable gcc/gnatbind" message... Specify:
export GNATBIND=/usr/bin/gnatbind

Once an initial gcc-3.1.1<ada,c> is built and installed in: <somewhere>/bin & 
<somewhere>/lib...  Specify:
export CC=<somewhere>/gcc
export GNATBIND=<somewhere>/gnatbind
To also get the tools (components) used by the Makefile:bootstrap that don't 
have a variable to hold the current absolute path...  Specify:
export PATH=<somewhere>:$PATH

At which point things get a little iffy during the initial stage of building 
for the stage1 compiler and tools.
The Makefiles hardcode: "../xgcc -B../" used AFTER the building of the stage1 
compiler and tools...

My mind "vapor locks" whenever I try to read these Makefiles - So if a 
Makefile expert could comment on the following:

1) Do away with the use of "GNATBIND" - it only handles "gnatbind" not the 
other gnat tools.
2) Provide ability to specify the absolute paths used during the initial 
building of the stage1 compiler and tools, perhaps like:
export INITIAL_ADA_PATH=<somewhere>
During initial build for stage1 would give:
ADAC=$(INITIAL_ADA_PATH)/$(compiler_that_understands_Ada)
and:
$(INITIAL_ADA_PATH)/gnatbind 
and:
$(INITIAL_ADA_PATH)/<any_other_Ada_tools_used>

I am using binutils-2.13 installed <somewhere>/bin & <somewhere>/lib
I am using the configure options to specify "as" and "ld" to be the 
<somewhere>/bin/as & <somewhere>/bin/ld
BUT, like the problem of not getting matching Ada tools above...

3) Provide ability to specify the absolute paths used during the initial 
building of the stage1 compiler and tools, perhaps like:
export INITIAL_BTOOLS_PATH=<somewhere>/bin
During initial build for stage1 (and other stages if not building new 
binutils in a composite tree), all the non-Ada tools (ar, nm, etc.) would be:
$(INITIAL_BTOOLS_PATH)/nm
$(INITIAL_BTOOLS_PATH)/ar
$(INITIAL_BTOOLS_PATH)/<whatever>
Note: this could also replace the "--with-as= & --with-ld=" configure options.
If building in a composite tree (I am not) - then once the stage1 build is 
complete, those things would become:
$(OUR_NEW_BTOOLS_PATH)/nm
$(OUR_NEW_BTOOLS_PATH)/as
$(OUR_NEW_BTOOLS_PATH)/<whatever>

Of course, all of the above suggestions would have to account for:

HOST_SYSTEM, TARGET_SYSTEM, and BUILD_SYSTEM when not building a native 
compilier / toolset.

I have repeated the bootstrap with the build directory totally seperate from 
the source directory - Once I finish groking this 30MB log file produced by 
"make -d -p bootstrap" I may have more information.

Humm.  I am using make-3.79.1-5 (Redhat-5) there is a make-3.79.1-8 
(Redhat-8), I'll try that also.
