Similar applies to:

include/util/delay.h.in
include/util/delay_basic.h

Well, "ANSI C" (aka. C89) is basically yesterday's hero
(current standard is ISO C99, upcoming is ISO C11), but this
was much easier to fix than you believed.

Fixed in SVN r2294.

Hello,

I filed this bug report to the Debian project:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=675759

The problem is the inline-attribute, that is not part of ANSI-C.

Here, the complete bug report:

-----
Hello,

the header file pgmspace.h uses the inline-attribute.
This attribute is not part of ANSI C.

My programs are compiled with the option -ansi.
Here is a minimal test program:

> #include <avr/io.h>
> #include <avr/pgmspace.h>
>
> int main (void)
> {
> while (1);
> return (0);
> }


Please compile this with:
$ avr-gcc -mmcu=atmega644p -ansi <file>

Compilation aborts because of the non-ansi include attribute in pgmspace.h

In GCC manual:
there is the predefined macro _STRICT_ANSI_ available, if parameter -ansi is used.
Please don't use the inline-attribute in case of _STRICT_ANSI_.

In avr-libc manual:
it is described, that this library has to be an ansi-c library.
This is described in chapter 1.2.

If you need more informations, please let me know.

Best regards
Bernhard
