i have a strange issue when cross compiling for arm: if i try to use 
errno (or build programs that uses it), i get (for example):

cmem.c:116: error: 'errno' undeclared (first use in this function)
cmem.c:116: error: (Each undeclared identifier is reported only once
cmem.c:116: error: for each function it appears in.)

and of course i have not forgotten to #include <errno.h>
what puzzles me is that the errno.h file (eldk/arm/usr/include/errno.h) 
only includes <asm-generic/errno.h> and that file is just a list of 
i also looked at the files in the include path, but it seems that the 
errno variable is not defined anywhere....

i tried to download the whole mailing list archives and look for a 
similar problem, but i found nothing...
can you please try to give me some hints?? thanks a lot!!
