21 | /* Unfortunately, 4.4 and emacs have conflicting uses of BIG_ENDIAN |
22 | and LITTLE_ENDIAN. Emacs assumes BIG_ENDIAN will be defined for | |
23 | big endian machines and not defined for little endian machines. | |
24 | endian.h in 4.4 defines both as values with BYTE_ORDER taking on | |
25 | the appropriate one. I see no way to reconcile the two. Just | |
26 | using the values from endian.h will break a little endian machine | |
27 | since BIG_ENDIAN is also defined. Undef'ing the values from | |
28 | endian.h (in the m- file) and redefining only one won't work since, | |
29 | for example, wait.h requires both be defined and have values. | |
30 | At the current time this is not a problem as we can hack around | |
31 | it. Emacs' only use of BIG_ENDIAN is in lisp.h and then only | |
32 | if NO_UNION_TYPE is not defined. By ensuring that NO_UNION_TYPE | |
33 | is defined, we avoid the issue. We also include endian.h now to | |
34 | make sure that the m- file doesn't override the correct value (in | |
35 | the big endian case). */ | |
