In simple words the error means there are two main functions since you have included file1.c twice here
Code:
gcc file1.c mathfun1.o file1.c -o file1

What you can do to solve your problem is build two object files mathfun1.o and file1.o and build the executable "file1" including both these object files. Your makefile would look something like this
Code:
CCFLAGS=-c -Wall
CC=gcc

file1:mathfun1.o file1.o
        $(CC) $^ -o $@

file1.o:file1.c
        $(CC) $(CCFLAGS) file1.c
mathfun1.o:mathfun1.c
        $(CC) $(CCFLAGS) mathfun1.c

clean:
        rm *.o file1

jmkmf

JMKMF(1)						      General Commands Manual							  JMKMF(1)

NAME

       jmkmf - runs jmake with the correct options

SYNOPSIS

       jmkmf [ top-level dir [ current dir ] ]

DESCRIPTION

       Jmkmf is a wrapper which calls jmake with the correct options, defining the symbols TOPDIR (location of the top-level directory) and CURDIR
       (current directory). The generated Makefile.SH is then ran through /bin/sh to produce a Makefile.

       Jmkmf is useful when you generate a makefile for the first time.

       When ran without arguments, jmkmf will scan the directories upwards, looking for a .package file marking the top of your sources.  It  will
       then derive the top-level directory and the name of the current directory by itself.

       Once you have a Makefile.SH generated by jmake, and have run Configure already, you can use make Makefile.SH to build the Makefile.SH again
       and make Makefile to run the Makefile.SH through /bin/sh.  To use the recursive commands, you have to append an 's' at the end of the  name
       as in make Makefiles.SH and make Makefiles.
