Hi!

I'm using GCC 2.95.2 (DJGPP) and having a problem with alignment.. Compiling
the following line:

kernel_info_page_t kernel_info_page __attribute__((aligned(PAGE_SIZE)))

(it's beginning of a structure) I get a message like:

global.c:31: warning: alignment of `struct kernel_info_page_t
kernel_info_page' is greater than maximum object file alignment. Using 4.

I haven't found any other way to set the alignment than with ugly assembler
macros. This compiled correctly on FreeBSD (with the same GCC version!
Though I don't understand how it's possible..)..

Any suggestions?.. BTW, how does GCC know what file format it's actually
going to be?..
