	Hi.
	I am a beginner with Flex. I am using flex-2.5.4a37.4 on fedora
core 5. i prepared a file lex.l (the contents of which are copied at the
end of the mail).
	then i issued the following commands :
	flex lex.l
	gcc -lfl lex.yy.c
	however the linker produced the error :
=09
	/tmp/ccodQ1yE.o: In function `main':lex.yy.c:(.text+0xfb3):
multiple definition of `main'
=09
/usr/lib/gcc/i386-redhat-linux/4.1.0/../../../libfl.a(libmain.o): first
defined here=20
	/usr/bin/ld: Warning: size of symbol `main' changed from 48 in
/usr/lib/gcc/i386-redhat-linux/4.1.0/../../../libfl.a(libmain.o) to 55
in /tmp/ccodQ1yE.o
	collect2: ld returned 1 exit status
=09
	can someone please point out my error?=20
	sincerely,
	rahul garg

	the input file lex.l is :

	%option nomain noyywrap
	delim [ \t\n]
	ws {delim}+
	letter [a-zA-Z]
	digit [0-9]
	id {letter}({letter}|{digit})*
	number {digit}+(\.{digit}+)?(E[+-]?{digit}+)?=20

	{id} {printf("identifier %s\n",yytext);}
	{number} {printf("number %s\n",yytext);}

	int count =3D 100;
	while(count>0){
