This is getting curious.

I searched the NT registry for 'gnatcom'; having gnatcom installed in
L:\Ada\GnatCom. I figured that this search would find the path if
it is stored in there. I found an entry in:

	HKLM\Software\Microsoft\Windows\CurrentVersion
	   \AppPaths\GnatCom1.3p\		

With a value for path that pointed into L:\Recycler\, ie the trash
for the drive that gnatcom was installed on.  Probably not good.
I didn't set it to point at the trash.  What's up?  IDK.

I deleted the entry and re-ran the gnatcom install.  The installer
did not re-create the entry.

So, I go to add\remove programs to try to uninstall gnatcom, and it
has some old pointer to a previous version of gnatcom on another
drive, and it won't uninstall.  (The registry is evil, particularly
if you don't uninstall before re-installing.)  

So, I go searching again for gnatcom in the registry, trying to find
this old pointer to another drive to get rid of it, and I find that
the gnatcom re-install has added a new setting:

	HKLM\SOftware\Ada Core Technologies\GNAT\Standard Libraries
		GNATCOM = L:\Ada\Gnatcom\Bindings

This wasn't there until I just reinstalled (I'm almost sure).
Will GWindows make install with this new setting and no 
Ada_Include_Path?  No, but it does give us something else 
interesting to consider:

gnatbind -aO./ -aO../../bindings/ -I- -x gnatreg.ali
gnatlink gnatreg.ali
ld: cannot find -lcomctl32
gnatlink: cannot call I:\GNAT\BIN\gcc.exe
gnatmake: *** link failed.
make[2]: *** [gnatreg] Error 4
make[2]: Leaving directory `L:/Ada/gwindows/tools/gnatreg'
make[1]: *** [gnatreg] Error 2
make[1]: Leaving directory `L:/Ada/gwindows/tools'
make: *** [tools] Error 2


This machine must be haunted.  This makefile ran yesterday
afternoon just fine without hitting this error. LibComCtl32.a 
is surely in my I:\Gnat\Lib\Win32 directory.  

I uninstall and reinstall GnatWin-3.15p.exe to see if that fixes
anything, then re-run Gwindows 'make ANSI=1 install'.  It works
fine with no ADA_INCLUDE_PATH now that the GnatCom registry
setting (above) is there.  Why it wasn't there yesterday is
just another one of those mysteries.
