Hi,
I have compiled your hello world program using Cygnus gnu-win32 b16 and
Colin Peters' mingw32 package (it is an interface for using crtdll.dll
instead of cygwin.dll) and I got an executable with a size of 3072 bytes
(stripped).
The section sizes are
..text 1024
..bss 24 (!)
..data 512
..idata 512
The size of headers is 1024.
(I don't understand that, adding all sizes I get 3096, but the
executable file
size is 3072, hello Cygnus, is there something wrong?)
