[Dev-C++] why do we have to rename free() ?

[Khalid El-K. <kha...@ho...>]

hi fellows,

when i checked a lot of big project's source codes, I have found them 
replacing basic funtion names with new function names, and sometimes with a 
new way of functioning for example:

free() -> OPENSSL_free()
malloc() -> gnew(type, number of blocks)

how can this be useful ?, does it have a thing to do with portability ?, and 
if not what's the difference in functionality ?

thanx in advance

Regards,
Khalid Al-Kary
