When I build this test case

$ cat hello.F95
!
! hello.F95
!
program hello
   ! implicit none
!   integer :: i
!   print *, 'i = '
!   read *,i
!   print *,i
   print *,'Hello World!'
end program hello

with gfortran-4 from gcc-4 package

    $ gfortran-4.exe hello.F95 -o hello_cyg

I obtain a file, hello_cyg.exe, of 381598 bytes.

If I use the build of gfortran I did at the end of August, when
GCC-4.3.2 was released [1], the result is

    $ gfortran hello.F95 -o hello_my

with hello_my.exe of 133075 bytes!

And

    $ objdump -h hello_cyg.exe

hello_cyg.exe:     file format pei-i386

Obviously, stripping hello_cyg.exe gives a file of only 99840 bytes!

It seems that gcc-4 uses '-g' even when it is not given on command
line!!!

IS THIS true?
Is there some problem here?


Cheers,
    Angelo.
