> I developped some time ago a set of routines for heap management (malloc, free, etc) on PICs.
> They work for PIC12 and PIC16 (mid-range) and PIC18 uCs (they may work for base-line PICs as well, but I doubt it will be any useful), with Hi-Tech PICC, Hi-Tech PICC-18 and Microchip MPLAB-C18 compilers.

better refer to lower PICs by their instruction size, PIC12 and PIC16 
have both 12 and 14 bit cores. I can't imagine a (usefull) heap 
management on a 12-bit core...

Personally I see little use for full heap management on embedded systems 
at all, mainly due to fragmentation. What type of applications would 
benefit from full heap management?

(NB full heap management == both malloc and free. I fully understand the 
utility of restricted heap 'management' == malloc only)
