- Subject: Possible bug in lbc?

The "arbitrary precision library for Lua" (lbc) contains a file number.h which has this in it:
#define LONG_MAX 0x7ffffff
The number 0x7ffffff is 134217727 in decimal (note only 6 Fs).
Other definitions of LONG_MAX (eg. in limits.h) have it as:
#define LONG_MAX 2147483647L /* maximum (signed) long value */
The number 2147483647 is 0x7FFFFFFF in hex (note 7 Fs, and this looks "more correct").
* Is this a typo in number.h (in the lbc library)?
* Should it be changed?
* Would the change make any difference to the behaviour of the library, which after all, handles numbers larger than 134217727?
* Or is there a valid reason the two LONG_MAX defines would have different values?
