new round of warning fixes. we are now down to 24 with Xcode on blender

alone with the following flags :
-Wall -Wno-char-subscripts -Wno-missing-braces.

the only one still worrying me is in rand.c line 57 :

rand.c:57: integer constant is too large for "long" type

but i have no clue about how correct cross-compiler and 32/64 bits friendly

see also my mail to commiter list for signed/unsigned issues
