I had the same problem some weeks ago!
For even aligned http data you should change the print statement
in file "makefsdata" at line 40 (or so):

     $file =~ s/\.//;
     $fvar = $file;
     $fvar =~ s-/-_-g;
     $fvar =~ s-\.-_-g;

     print(OUTPUT "__attribute__ ((aligned (2))) static const char 
data".$fvar."[] = {\n");

     $i = 0;
     while(read(FILE, $data, 1)) {


The added
     __attribute__ ((aligned (2)))
works with gnu-gcc (linux 2.4).

Hope it helps!

/Horst
