The value of an enum changed (math is hard). This often requires
a major bump (see below):
diff -pu -r /usr/local/include/Inventor/C/base/string.h
/usr/ports/pobj/coin-4.0.9/fake-amd64/usr/local/include/Inventor/C/base/string.h

This change shrinks the buffer in the public struct cc_string:
struct cc_string {
char * pointer;
size_t bufsize;
char buffer[CC_STRING_MIN_SIZE];
};
On all our platforms CC_STRING_MIN_SIZE would previously work out to 128
and now it is 112 on LP64 and 120 on ILP32. This is an ABI break
requiring a major bump, as applications expecting to be able to write
CC_STRING_MIN_SIZE to buffer need to be recompiled to avoid writing past
the end.
i don't think this is actually used this way anywhere. We should still
bump the libCoin major.

Not against it, but there is no static lib and it's not a header-based
library as far as I can see, so I see no need for a bump of the consumers.
The shlib major bump alone should do the trick.
ok tb
