help!


(1):
i downloaded & installed gpp 3.1 and all other associated zips recently.now when i compile with:
gpp -o file.exe file.cpp

 it tells me:

"In file included from c:/djgpp/lang/cxx-v31/backward/iostream.h:31,
                 from c.cpp:3:
c:/djgpp/lang/cxx-v31/backward/backward_warning.h:32:2: warning: #warning This f
ile includes at least one deprecated or antiquated header. Please consider using
 one of the 32 headers found in section 17.4.1.2 of the C++ standard. Examples i
nclude substituting the <X> header for the <X.h> header for C++ includes, or <ss
tream> instead of the deprecated header <strstream.h>. To disable this warning u
se -Wno-deprecated."

i use #include<iostream.h> which i think is the cause of this error.
the prog however compiles and i do get the exe.
i tried using #include<iostream> as suggested but it says:
" `cout' undeclared (first use this function) ".......etc

i looked into C:\DJGPP\include and it doesnt have iostream.h
i copied the file "iostream" from C:\DJGPP\lang\cxx-v31 into C:\DJGPP\include but that doesnt work, it gives the same 'undeclared...' error.

i copied the file "iostream.h" from C:\DJGPP\lang\cxx-v31\backward into C:\DJGPP\include and then compiled but again the 'deprecated header' error

i commented out #include:    
//#include<iostream.h>, again the 'undeclared...' error.


i've read the faqs but they dont help.is it some library error?.i really dont know what to do.the progs compile and i do get the exes but the message constantly nags.

could someone plz tell me what to do?
someone mentioned something about explicitly stating the namespace. i dont know what that is.


(2):
when  i compile and get the exe, the exe file size is an unbelievable 1.42MB!!!
ive used: gpp -o file.exe -s file.cpp , the -s switch, and the file size reduces to 255KB which again i think is really too much.when i used an earlier version of DJGPP i did not get such huge file sizes
now every time i have to use UPX to reduce file size which again comes to around 90KB.
can someone please tell me a way to reduce the initial file size.are there any more switches besides '-s'

if you are still with me thank you very much for going through this long email.i'll be  grateful if you can help me.
 thanks in advance.
