Yes, that illustrates the idea. However, this implementation suffers
from the use of an #ifdef where none is actually needed. Instead, you
can create your own source file which defines the header; this could
be then even in it's own segment, say:
your_header.c:
struct your_header {
u_int32[8];
} your_header __attribute__ ((__section__ (".your_hdr")));
All that is needed then is to make the linker place this segment in
front of the text segment.
This avoids an ugly #ifdef, and also modifications in the common code.
Best regards,
Wolfgang Denk
