Misconception?
And you have a master's degree in CS?

It doesn't say that in an ANSI C manual, however it
does say that you must place platform specific code in
an #ifdef capsule.

Is it so hard to understand that if you do this;
#ifdef WIN32
     puts("YEAH!! You compiled with a Win32
compiler!");
#else
#ifdef DOS32
     puts("BOOH!! You compiled with a DOS compiler!");
#endif
#else
    puts("Wha? You compiled a fplatform other that DOS
and Windows! So I'm using ANSI code only! Yipee");
#endif

You code will compile on any platform?
Sure, if the compiler used was not for DOS, Windows or
Linux, you can place some ANSI C printf's that say
"Sorry! No graphics for this unknown platform! write
your own code!".
But atleast you support EVERY ANSI C compiler for Dos,
WIndows and Linux, and not just a few of them (Take
Vector C, extremely fast new compiler, it's extremely
fast with floats and memory handling, I can never use
it with Euphoria. Or VC++? Or Symantec C? Or MingW?
Cygnus? Or a C interpreter? Etc...)

Take a good look at how Pete's Portable Euphoria does
it:

#ifdef ALLEGRO
  #include <allegro.h>
#endif

His code compiles with LCC Win32! While it was written
for DJGPP!!!!
It's ANSI C code and does everything Euphoria does
(except for a few functions).
Compile his code with DJGPP and you aotumatically can
use Allegro graphics!
Compile with LCC and you can't!
Simple as that!
But atleast it compiles!!!
And you can add your own graphics library for the
platform you want.

If it says:
#ifndef WIN32
#ifndef DOS32
/* Not Dos and not Windows */
#include <drawing.h> /* Gameboy */
#include <cgb.h>

int pixel(int, int)
{
    LCD_OFF;
    /* Write the pixel on the gameboy */
    LCD_ON;
}

#endif
#endif



Easy huh?


Just do it, it'll make us all feel better.
Include allegro for DOS if DJGPP has being recognised,
otherwise use your own SVGA routines.

Euphoria don't allow graphics in Win32 anyways, so
what the big deal?
