You are right, I found this faq right now:

May I suggest that you add "defined(__GNUC__)" to this test as well?
(This symbol is defined by all gcc variants, as far as I know.)

Both the symbol MSP430 and __MSP430__ are generic and may very well be
defined by other (present or future) compilers, in which case you will
mistake them for GCC.

For AQ430, the mnemonic is:  __AQCOMPILER__  
It is defined automatically inside the compiler, so there is no need 
to include any special .h file:
#ifdef __AQCOMPILER__
....
#endif

Hi,

because Win-XP did not flushed the buffer the last version was wrong; 
the actual version is:

Hi,

ok, i forgott a flag in case a right compiler can be found:

How does it fail?

Try to compile the following variant -- I've added #error:s to it so
that it will report the result little bit more clearly.  I've also
added one case at the bottom, if it triggers then you can try to
change the initial #ifdef to "#if defined(__IAR_SYSTEMS_ICC__) ||
defined(__IAR_SYSTEMS_ICC)", but hopefully this will not be necessary.

When I apply this to our old compiler it reports:

#      error "V1.xx of the compiler."
-^
"def.c",9  Error[141]: #error '"V1.xx of the
compiler."'

Please let me know what happends when you compile the file.

This does not work; it fails for the 1.26 version.

Hi,

ok,  it works :-)
