Flex does generate a header file, which also holds the definitions for the 
start 
conditions. You can try it out by running the following:

flex --header-file=lex.yy.h test.l


If you defined starting conditions on your test.l file then the lex.yy.h will 
hold the definitions. Unfortunately they are enclosed in a #define statement.
