compiling c and c++ source same time

[Suman Kumar Ray]

Alex,
   I am using g++ as linker mainly because it will add
all c++ library by default, whereas if I use gcc, I
have to explicitly pass those libraries in option. At
least this behavior, I have found in cygwin. My doubt
is when we can't use gcc as a compiler for c++ file. I
mean, I have seen e.g. if I use class etc. in file
a.C, and if I say gcc -c a.C, it can compile the file.
Then as a compiler front end ( not as a linker,
because g++ passes
extra library by default), why do we need g++ ? 
Regards,
Suman
