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

Dear Danny,

     From your analysis of the problem I presented, I concluded that including
the libstdc++.a library when compiling cpp programs with gcc-3.2-1, might solve
the problem.  I tried this and can now report the following.

The command

gcc -O2 -mno-cygwin -mwindows short.cpp  \
-lkernel32 -luser32 -lgdi32 -lwinspool -lstdc++  \
-lcomdlg32 -ladvapi32 -lshell32 -lole32 -loleaut32 -luuid -lodbc32 \
anv.res -o short 

produces the following error messages with gcc-3.2-1

/DOCUME~1/Mark/LOCALS~1/Temp/ccj6o4RG.o(.text+0x2f8):short.cpp: undefined reference to `operator new(unsigned)'
/DOCUME~1/Mark/LOCALS~1/Temp/ccj6o4RG.o(.text+0x329):short.cpp: undefined reference to `__cxa_begin_catch'

make: *** [short] Error 1

     However, I discovered that without the -mno-cygwin option, things compile
and run perfectly.  Is it possible that a different libstdc++.a is used with the
-mno-cygwin option?
