4MB?!??!?!?! What compiler?
I just tried with CygWin, using -o2 with gcc 3.4.4 and got:
$ ls -l hello*
-rwxrwxrwx 1 Bones None 86 Jan 29 20:26 hello_c.c*
-rwxr-xr-x 1 Bones None 8.7K Jan 29 20:29 hello_c.exe*
-rwxrwxrwx 1 Bones None 113 Jan 29 20:31 hello_cpp.cpp*
-rwxr-xr-x 1 Bones None 466K Jan 29 20:32 hello_cpp.exe*
But on Linux, using gcc 3.3.6, I got
[EMAIL PROTECTED] ~ $ ls -l hello*
-rwxr-xr-x 1 bmccoy users 6083 Jan 30 01:48 hello_c
-rwxr-xr-x 1 bmccoy users 86 Jan 30 01:48 hello_c.c
-rwxr-xr-x 1 bmccoy users 7834 Jan 30 01:48 hello_cpp
-rwxr-xr-x 1 bmccoy users 113 Jan 30 01:48 hello_cpp.cpp
Why does CygWin produce such a large C++ binaries?
