User level Macros for Endianess

[Stephane GEORGES]

I use my own executable compiled by GNU before compiling anything else:

bigendian.c
-----------

int main()
{
  unsigned short val = 0x0011;
  unsigned char* str = (unsigned char*)&val;
  if ( str[0] == 0x00 )
    return 1;
  else
    return 0;
}

in my GNUmakefile
-----------------

- one rule to compile bigendian.c if exe not compiled
- one rule testing the return value of exe and setting

    MEMORY_IS_LITTLE_ENDIAN or MEMORY_IS_BIG_ENDIAN

That way I do not need to look for the right MACRO on the right SYSTEM.

I compile my code on IRIX (SGI), Solaris (SUN), intel Linux and LinuxPPC.
