C code in Dev-Cpp

[waltbrad]

What can I do to get Dev-Cpp to compile C code? Whenever I try
compiling C code the compiler complains about the headers.

For instance the code:(I do name the code with extension.c)

#include <stdio.h>
#include <string.h>

int main(int argc, char **argv)
{

char buffer[100];

strcpy(buffer, argv[1]);
printf("%s\n", buffer);

}

gives me the errors:

Umm.. "compilatio n successful". Those are warnings. Those warnings are
saying that stdio.h, stdarg.h and string.h contain GCC specific instructions
(#include_next and long long) that are not ISO C90. Yet it would seem that
you continue to get your program. Warning != error.

What's more the reference to C90 proves that the OP is compiling C not C++.

To the OP, -Wall (i.e. turn on all warnings) is the problem. Personally
I wouldn't be happy with a compiler that couldn't compile standard C
header files without warnings but it's your choice.

I wonder if turning on 'C99' would help.
-std=c99
or:
-std=iso9899:199 9
or:
-std=gnu99 // C99 + GNU extensions

the last warning is due to declaration of main as returning int but
providing a body that returns nothing.Put this line before '}' of the
main function:

return 0;

and one warning is reduced.
