error: redefinition of 'int main()'

i keep getting error in code during verify/compile:

quote

" in function 'int main()':
error: redefinition of 'int main()' "

am supposed doing alarmclock/stopwatch type of deal...
and trying code compile , run can test if it's adding , subtracting correctly, , make sure coded interrupts work correctly, , figure out how can control lines on serial lcd connect.

***plus*** apologize of volatile declarations, compiler not let me not declare again within voids.

also,
am allowed use "goto clock_set" within void loop?  everytime do, says:

quote

in function 'void loop()':
error: label 'clock_set' used not defined in function 'int main()':

you've redefined "main".
arduino sketches don't have "main", it's provided you.

you've got odd scoping going on volatiles.

you should never use "goto" - make fairies cry.
