I did try the -v, but not after -largs. But the problem is now
solved now, by fixing the project file:

The key turned out to be the following 3 lines in the
project file (that I had differently):

  package Builder  renames AVR.Builder;
  package Compiler renames AVR.Compiler;
  package Binder   renames AVR.Binder;

Evidently, this sets things up a lot of things:

$ avr make
avr-gnatmake -XMCU=atmega328p -Ptestavr.gpr
avr-gcc -c --RTS=rts/avr5 \
  -gnatec=C:\WinAVR-20100110\lib\gnat\gnat.adc \
  -gdwarf-2 -gnatwp -gnatwu -gnatn -gnatp \
  -gnatVn -Os -gnatef -fverbose-asm -frename-registers \
  -mmcu=atmega328p -gnateDMCU=atmega328p \
  -fdata-sections -ffunction-sections -I- \
  -gnatA F:\home\wgay\avr\testavr\testavr.adb

The "avr" is just my wrapper script to fix the PATH 
in cygwin for the WinAVR tools.
