Two header files - limits.h and stdint.h have everything the compiler can know about integer sizes in bits, usually WORD_BITS and CHAR_BITS are used to define the rest of the macros.

You may have some compiler options to control long int size, I do not know.

Start with that. BTW you should have tried to read these and some other header files just to get an idea about what settings your compiler can and does employ.

There should be/is a man page for each of the important header files like math.h

NAME
inttypes - fixed size integer data types SYNOPSIS
DESCRIPTION
This header file defines integer data types of various sizes. By using the data types defined in this header file, developers can be assured that the data types will have the same properties and behavior on different systems. Since not all implementations are required to support all of the integer sizes defined in this manual page, the proper way to see if a par- ticular size of an integer is supported on the current implementation is to test the symbol that defines its maximum value. For example, if tests false, then that implementation does not support 64-bit unsigned signed integers. The header includes header. This header file defines the following data type. structure type that is the type of the value returned by the function The following macros can be used as formatting options with the family of functions (see printf(3S)). These macros are used to select the correct formatting option for the integer data types defined earlier in this manual page. The following macros can be used as formatting options with the family of functions (see scanf(3S)). These macros are used to select the correct formatting option for the integer data types defined earlier in this manual page. Notes The formatting options for the family of functions all begin with whereas the formatting options for the family of functions all begin with These formatting strings may not be interchangeable. EXAMPLES
The following example shows how to use one of the print formatting options with the function. AUTHOR
