[Mspgcc-users] strange problem with __FUNCTION__

[nobodyO]

Hi,

when i use

#   ifndef __FUNCTION__
#      define __FUNCTION__ __func__
#   endif

before

  _BIC_SR_IRQ (LPM4_bits);  // line 42

mpsgcc reports 

signal.c:42: syntax error before "__func__"

although i can find no reason why the define should be an error
and the ifndef block works without problems on PC and ARM9
in kernel and user space.
I reduced the problem to this minimal example file tmp.c:

#   include <io.h>
void
kernel_panic (void)
{
#   ifndef __FUNCTION__
#      define __FUNCTION__ __func__
#   endif
  _BIC_SR_IRQ (LPM4_bits);   
  return;
}

and i compiled with 

msp430-gcc -mmcu=msp430x168 -O2 -Wall -g -c -o tmp.o tmp.c

Any ideas what's wrong?

Regards,

Rolf
