Hello.

I'm porting several peaces from FreeBSD to Newlib. FreeBSD's code needs 
ntons() and htonl() functions. These functions aren't the part of Newlib.
To implement these functions in the machine independent manner I need 
functions like word_swap, etc or macros like BIG_ENDIAN. I can implement 
my own private versions of htons(), etc using these macros. But may be 
it is more correct to to create file like machine/endian.h.
What is the best that I can do?

Thanks.
