Or look in limits.h yourself for FLT_DIG and DBL_DIG

On POSIX-compliant UNIX boxes POSIX requires those to be at least

mkdep(1)						      General Commands Manual							  mkdep(1)

NAME
mkdep - generate dependency list from a C program SYNOPSIS
mkdep [-a] [-f depend_file] [-p] [cc_options] file... The mkdep command generates a dependency list file from a C source program. OPTIONS
Causes mkdep to append its output to the end of the dependency file instead of creating a new dependency file. If the dependency file does not exist, mkdep creates it. Specifies a name for the dependency file; overrides the default file name Inhibits mkdep from appending the suffix to the names of object files listed in the output. DESCRIPTION
The mkdep command uses cc(1) to compile a list of dependency files required to build the named C program file or files. The list is for- matted so that it is suitable for inclusion into a makefile for make(1). Duplicate dependency listings for a given program are included only once in the output. You can specify C compiler options by including them in the command line; mkdep passes all unrecognized options through to the compiler. By default, mkdep writes to a file named -f option to specify an alternative output file name. EXAMPLES
The following example illustrates the use of mkdep with the -p option: % cat hello.c #include <stdio.h> main() { printf("%s0","Hello World!"); } % mkdep -p -f hello.depend hello.c % cat hello.depend hello: hello.c /usr/include/stdio.h /usr/include/standards.h hello: /usr/include/sys/types.h /usr/include/standards.h hello: /usr/include/mach/machine/vm_types.h /usr/include/sys/limits.h hello: /usr/include/standards.h /usr/include/machine/machlimits.h hello: /usr/include/sys/syslimits.h /usr/include/float.h hello: /usr/include/standards.h /usr/include/fp_class.h hello: /usr/include/machine/machtime.h SEE ALSO
Commands: cc(1), make(1) mkdep(1)
