Error: installation problem, cannot exec `cc1' ..'as', etc..

[steroidmicros]

After happily using GCC-3.2.2 compiled for the m68k (MingWin) for many 
years, I ported it to a new WinVista PC where it worked fine for a 
month. Then, after some Vista problems, I reinstalled Vista and 
installed GCC exactly as I had done previously and it no longer compiled:

m68k-elf-gcc -I"C:\SBCToolsV3\boards\wildfiremod\dbug\rtl\include" 
-I"C:\SBCToolsV3\boards\wildfiremod\dbug\tcpip\include" -O0 -g3 -Wall -c 
-m528x -o"main.o" "../main.c"
m68k-elf-gcc: installation problem, cannot exec `cc1': No such file or 
directory

This is definitely a path problem. When I placed 'cc1' in the bin 
directory (on the PATH) and attempted to compile, it no longer 
complained about 'cc1'. Instead, the error changed to:

m68k-elf-gcc -I"C:\SBCToolsV3\boards\wildfiremod\dbug\rtl\include" 
-I"C:\SBCToolsV3\boards\wildfiremod\dbug\tcpip\include" -O0 -g3 -Wall -c 
-m528x -o"main.o" "../main.c"
m68k-elf-gcc: installation problem, cannot exec `as': No such file or 
directory

The strange thing is that when I enter "-print-search-dirs" at the 
command prompt from the corresponding directory,  m68k-elf-gcc appears 
to be aware of the correct 'cc1' and 'as' paths:

C:\SBCToolsV3\workspace\DemoAD_dbug_wfmod\Debug>m68k-elf-gcc

I am baffled as to why GCC cannot find the .exe's when it claims to have 
their search paths???

Attempts to use the -Bprefix option 
(http://gcc.gnu.org/ml/gcc-help/2007-09/msg00172.html) failed, possibly 
because I do not know how to use it correctly:

C:\SBCToolsV3\workspace\DemoAD_dbug_wfmod\Debug>m68k-elf-gcc 
-B"C:\SBCToolsV3\co
mpiler\m68k-elf-3.3.2\lib\gcc-lib\m68k-elf\3.3.2\" 
-I"C:\SBCToolsV3\boards\wildf
iremod\dbug\rtl\include" 
-I"C:\SBCToolsV3\boards\wildfiremod\dbug\tcpip\include"
 -O0 -g3 -Wall -c -m528x -o"main.o" "../main.c"
m68k-elf-gcc: no input files

Can anyone help me?
