.text is the executable machine code representing your C code.
.rdata is read-only data (eg strings).
.data is the space for initialised variables.
.sdata is the space for initialised variables smaller than a certain
size in bytes (default 8).

TEXT = .text
DATA = .data
BSS = the .bss section, which is space for uninitialised variables.
This area is cleared with zeroes when the program image is loaded, but
the zeroes aren't stored in the game file itself (since this would be
silly).


Dunno about the rest of the Q's though...
