As a piece of very important trivia, note that Wolfgang's example
initialized the variable in the declaration.  If you don't initialize the
variable, it won't end up in the desired section.  Yes, that is in the gcc
manuals, just easy to miss :-).

  Thanks- I've been surprised by this cute little 'feature' on other
compilers.  Discovering it the hard way was a 'fun' way to blow a
day or two.  ;)

Actually it should be no big surprise. I  think  every  (?)  standard
conforming  C  compiler  will  put  uninitialized  data  into the BSS
segment (usually .bss in the linker scripts).

P.S.  Looking through past postings, are gcc 2.95.3 and binutils-2.10.1
       still the recommended versions for embedded use?  Has confidence
       in more modern versions been established yet?  I'll choose
       reliability over optimization every time, but i've heard of subtle
       issues with 2.95.3 as well.

We used 2.95.3 a long time for the ELDK, now we use 2.95.4.

No problems were reported (yet).

Best regards,

Wolfgang Denk
