Dev-cpp - compiler options

I just recently switched to Dev-Cpp 4.9.9.2 and I'm wondering how I can force the compiler to conform to ANSI C and such things. As it is now, it lets me get away with quite a lot of strange things. ;) I of course tinkered with as much as I could in all the menus, but without much luck. Do I need to pass parameters to the compiler manually (I did notice a few parameter boxes here and there)? I'm sure there must be a guide to this somewhere? Please point me in the right direction!

Happy new year, and thanks for all previous replies to my threads! (I do read everything you guys write, it's just that I've been a bit lazy posting back. ;)

You should be able to set up any additional command line parameters you want.
I use these when compiling for ANSI, and wanting maximum diagnostics
-W -Wall -ansi -pedantic -O2

All the gory details on what all available gcc compiler options are here
http://www.gnu.org/software/gcc/onlinedocs/

The Compiler Options dialog box lets you tweak lots of things as well.

D*mn, you guys are fast. Thanks!

The -pedantic parameter actually gives me a lot of warnings in stdio, about long long not being allowed and such. I find this very odd. I believe long long is [edit]C99[/edit], but still, what can I do about headers?

Really? Can you post them?

Try compiling your program from the command line, too.

Here's the compiler output from Dev-Cpp:

As soon as I add -Wno-long-long everything is fine.

Did you try the flag -std=c99 ??

Sorry, my -ansi somehow got lost in the mix. :S It's supposed to be ANSI C, nothing else. Yes, -std-c99 also solves the problem. :)
