* libc/include/machine/ieeefp.h (__IEEE_BYTES_LITTLE_ENDIAN):
Define for little endian ARMs.
* libc/stdlib/mprec.h (Storeinc): Use little endian version if
__IEEE_BYTES_LITTLE_ENDIAN is defined.
2001-06-11 Danny Smith <dannysmith@users.sourceforge.net>
* /libc/include/ctype.h (is* and to* macros): Do not define if C++.
