Compiler claims to be ANSI C level 1

Compiler names are at least 64 chars long
Preprocessor names are at least 64 long

SIZES
char = 8 bits, unsigned
short=16 int=32 long=32 float=32 double=64 bits 
long double=128 bits
char*=32 bits
int* =32 bits
func*=32 bits
Type size_t is unsigned int/long
Type wchar_t is signed int/long

ALIGNMENTS
char=1 short=2 int=4 long=4
float=4 double=8
long double=16
char*=4 int*=4 func*=4

CHARACTER ORDER
short: AB
int:   ABCD
long:  ABCD

PROPERTIES OF POINTERS
Char and int pointer formats seem identical
Char and function pointer formats seem identical
Strings are shared
Type ptrdiff_t is signed int/long
Dereferencing NULL causes a trap

PROPERTIES OF INTEGRAL TYPES
Overflow of a short does not generate a trap
Maximum short = 32767 (= 2**15-1)
Minimum short = -32768
Overflow of an int does not generate a trap
Maximum int = 2147483647 (= 2**31-1)
Minimum int = -2147483648
Overflow of a long does not generate a trap
Maximum long = 2147483647 (= 2**31-1)
Minimum long = -2147483648
Maximum unsigned short = 65535
Maximum unsigned int = 4294967295
Maximum unsigned long = 4294967295

PROMOTIONS
unsigned short promotes to signed int/long
long+unsigned gives unsigned int/long

PROPERTIES OF FLOAT
Base = 2
Significant base digits = 24 (= at least 6 decimal digits)
Arithmetic rounds towards nearest
   Tie breaking rounds to even
Smallest x such that 1.0-base**x != 1.0 = -24
Smallest x such that 1.0-x != 1.0 = 2.98023259e-08
Smallest x such that 1.0+base**x != 1.0 = -23
Smallest x such that 1.0+x != 1.0 = 5.96046519e-08
(Above number + 1.0) - 1.0 = 1.19209290e-07
Number of bits used for exponent = 8
Minimum normalised exponent = -126
Minimum normalised positive number = 1.17549435e-38
The smallest numbers are normalised
Maximum exponent = 128
Maximum number = 3.40282347e+38
Overflow doesn't seem to generate a trap
There is an 'infinite' value
Divide by zero doesn't generate a trap
Arithmetic uses a hidden bit
It looks like single length IEEE format
   though the normalisation is unusual

PROPERTIES OF DOUBLE

(Above number + 1.0) - 1.0 = 2.2204460492503131e-16
Number of bits used for exponent = 11
Minimum normalised exponent = -1022
Minimum normalised positive number = 2.2250738585072014e-308
The smallest numbers are normalised
Maximum exponent = 1024
Maximum number = 1.7976931348623157e+308

There is an 'infinite' value
Divide by zero doesn't generate a trap
Arithmetic uses a hidden bit
It looks like double length IEEE format
   though the normalisation is unusual

PROPERTIES OF LONG DOUBLE
Base = 2
Significant base digits = 107 (= at least 31 decimal digits)
Arithmetic rounds towards nearest
   Tie breaking rounds to even
Smallest x such that 1.0-base**x != 1.0 = -107

(Above number + 1.0) - 1.0 = 1.232595164407830945955825883254353e-32
Number of bits used for exponent = 11
Minimum normalised exponent = -916
Minimum normalised positive number = 1.805194375864829576069262081173747e-276

*** WARNING: Possibly bad output from printf above
    but value was an unusable number

Overflow doesn't seem to generate a trap
There is an 'infinite' value
Divide by zero doesn't generate a trap
Only 118 of the 128 bits of a long double are actually usedIt doesn't look like IEEE format

Float expressions are evaluated in float precision
Double expressions are evaluated in double precision
Long double expressions are evaluated in long double precision
Memory mallocatable ~= 340 Mbytes
