Subject: Problem compiling cpp programs with gcc-3.2-1

     The problems described below appeared after I upgraded to the latest
versions of the cygwin release.  It disappeared when I went back to gcc-2.95.3,
leaving all the other utilities at the latest version.  This suggests to me the
problem lies in gcc-3.2.1, or in how I have it configured.

Why won't 
gcc simp.cpp -o simp 

compile the incredibly simple program below without generating e-messages like

/DOCUME~1/Mark/LOCALS~1/Temp/ccRtp1xR.o(.eh_frame+0x11):simp.cpp: undefined reference to `___gxx_personality_v0'
collect2: ld returned 1 exit status

     Why must I replace gcc with g++ or c++ after upgrading from gcc-2.95.3-5 to
3.2.1 ?

Are error messages like

/DOCUME~1/Mark/LOCALS~1/Temp/ccBuHJFC.o(.text+0x948):anv.cpp: undefined reference to `operator new(unsigned)'
/DOCUME~1/Mark/LOCALS~1/Temp/ccBuHJFC.o(.text+0x979):anv.cpp: undefined reference to `__cxa_begin_catch'
/DOCUME~1/Mark/LOCALS~1/Temp/ccBuHJFC.o(.text+0x9a5):anv.cpp: undefined reference to `__cxa_end_catch'

in response to compiling a slightly more complicated cpp program with gcc
related, or due to something else?  My slightly more complicated program will
compile if I replace gcc with g++, but the compiled program bombs immediately.

     Is there a simple fix other than using gcc-2.95.3-5 instead of 3.2-1?

Thank you, Mark Schoenberg
