POSIX - max line length?

Is there a defined line length maximum in POSIX.1? I want to get in the habit of writing platform independant code. I'm looking to do something like this for a simple text editor:

char line[MAX_LINE_LENGTH];

Assuming MAX_LINE_LENGTH is defined by the standard. Is this possible or should i just throw a magic number in my program, like 4096.

I've never known of a line length limit.I know early implementations of the vi editor had a line limit of 2046, but any good editor will have no limit. I just tried it out with vim and it opend a 96M text file with only a single line. Instead of declaring a char[] to hold the line, it should probably be dynamic
