Sigh, sigh, sigh. No.

char = 1 byte always.
short = 2 byte always
long = 4 byte always
long long = 8 byte always (as of recently)
BUT *unspeficied variety* int in DJGPP is hardcoded to a long.

and for kicks:
short float = 32 bit IEEE float always (no matter what type of FPU)
double (float) = 64 bit IEEE float always
long double (float) = 80 bit IEEE float always
float (unspecified) in DJGPP has a size that can be defined by context
or compiler flags, but if it has a choice, 64-bit.
