THE -o BEFORE prog.exe SPECIFIES THE NAME OF THE OUPUT.  THE FIRST
RUN YOU DID HAD NO OUTPUT FILE SPECIFIED SO g++ WOULD CREATE a.out
THE SECOND RUN WOULD CREATE prog.exe

THE ABOVE IS THE PREPROCESSOR BEING INVOKED TO PARSE prog.cpp
INTO c:/djgpp/tmp/ccaaaaaa.ii

THE ABOVE IS THE INCLUDE SEARCH DONE BY THE PREPROCESSOR
THE ARE NO ERROR MESSAGES SO THE PREPROCESSOR IS HAPPY

THE NEXT IS THE COMPILER COMPILING c:/djgpp/tmp/ccaaaaaa.ii
INTO c:/djgpp/tmp/ccaaaaaa.s

QUESTION FOR ANYBODY. WHAT IS THE REFERENCE IN THE ABOVE LINES
TO prog.cc? IS IT JUST A TAG BEING PAST ALONG? IS IT WHY GDB WON'T
USE .CPP FILES?

NEXT IS THE ASSEMBLER c:/djgpp/tmp/ccaaaaaa.s TO 
c:/djgpp/tmp/ccaaaaa1.o THE OBJECT FILE
>  as -o c:/djgpp/tmp/ccaaaaaa1.o c:/djgpp/tmp/ccaaaaaa.s

FINALLY THE LINKER  CREATING prog.exe IN THE CURRENT DIRECTORY

ONCE AGAIN NO ERROR MESSAGES SO THE LINKER THINKS IT'S DONE ITS
JOB.

THE COMMENTS ABOVE ARE FOR RYUJI JUST SO THAT HE KNOWS WHATS HAPPENING
IN THE PROCESS AND MIGHT NOTICE SOMETHING?

ANYWAY MY 2 BITS. (OR 2K BYTES AS THE CASE MAY BE:-)

I would exit windows to the command line.
Create a myprogram directory, move myprog.ccp to it.
run the following commands

g++ -v -c myprog.cpp
then
g++ -v myprog.o -o myprog.exe

after that 
dir

and see what files you've got
good luck
Charles
