2019-10-20 - Pedantic 
------------------------------------------------------------------- 
Today i was reading a bit about GCC and all the compiler options it 
has. And with all that i was reading, i was playing around a bit 
with a little C program i made earlier.

I was mostly figuring/wondering to which standard/style my C 
programming would conform to. I think i was mostly adhering to the 
C99 standard, but i think i was writing a bit of a mishmash of 
everything.

So as a small exercise, i turned on the -ansi or -std=c90 and the 
-pedantic flags of GCC, and tried to recompile. This resulted in 
some compiler errors and warnings, mostly caused by the following:

- Commenting using //comments.
- Mixing declarations and code. In ansi C, declarations are 
  placed at the top of a block/function.
- Combining declaration and initializations; int x=0;

And that was pretty much all of it... My program was of course 
pretty simple.

Anyhow, despite following old standards this way, at least i am 
following some standard, and don't mix up three different things. 

I'll continue reading about more GCC stuff. But at the same time i 
wonder if i can also find a good smaller/lightweight C-only 
compiler. Maybe Tcc by Fabrice Bellard?
