Try:

main() {
}

_main() {
}

__main() {
}

on arm, and then compile with -fleading-underscore and -fno-leading- 
underscore and then examine each case by hang.  main() should have  
the call the __main, and none of the others should.  Also, the change  
I imagine your contemplating doesn't handle USER_LABLE_PREFIX set to  
"foobar", as the assembler name for main would be foobarmain.  If you  
strncmp user_label_prefix and then check main, you'd be set I think.
