hard to find the correct include files at compile time

Hello,

I have a strange behavior while compiling an avr project with code-blocks.
In my code I include the <avr/pgmspace.h>. The file is situated in
/usr/lib/avr/include/avr/pgmspace.h

The pgmspace.h includes <inttypes.h>. The problem is that at compile time
the wrong inttypes.h is included -- the one which is part of the x86
architecture. I am forced to make an explicit statement (#include
"/usr/lib/avr/include/inttypes.h") to solve the issue.

Is it a normal behavior ? Should I set a compile-time variables in
code-blocks so that the correct file is included ?

As a side-note the pgmspace.h includes also <stddef.h>. I am not sure
whether the correct one is charged. To be sure I also make an explicit
statement (#include "/usr/lib/gcc/avr/4.7.2/include/stddef.h"). What is
more strange is that both files are not in the same part of the directory
tree. Is there a logic behind it that I cannot understand ?

Best regards,
