 		 #115539 - Perhaps it is?
Responding to: ???'s previous message
Matthias Arndt said:
That's too bad! But why did Atmel once declare a header include to be compatible with both SDCC and Keil C?

Perhaps because they made it so!

eg
Save This Code
#if defined __C51__
// Keil C51-style stuff
#elif defined SDCC identifier
// SDCC-style stuff
#else
#error Unrecognised compiler!
#endif
(I don't know what the appropriate symbol is to identify the SDCC compiler - RTFM)

I strongly recommend this approach to make your code compiler-independent.

  • You should define your own data types of known size & "signedness"; eg, U8, S16, U32

  • You should "encapsulate" all the special keywords in macros that will expand to the appropriate compiler-specific syntax

  • Note the #error clause at the end - to ensure that you have specifically handled the actual compiler in use
