compiling c and c++ source same time

compiling c and c++ source same time

[Suman Kumar Ray]

Hello,
 I have a requirement that if a directory contains
c and c++ sources, c files will be compiled by c
compiler and c++ by c++ compiler. I can handle it
through script, but I am curious to know if I use
gcc for compiling all files and g++ for linking all
object files, can gcc handle compilation of c++ files
for all scenario. In gcc manuals it says
"GCC recognizes files with these names and compiles
them as C++ programs ... However, C++ programs often
require ... a compiler that understands the C++
language". Does it mean, compiling (not linking) a c++
file by gcc and by g++ is not same thing ?
 Thanks in advance.

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
