Don't put the header file in the compile command.
C:\Compiler\lyass1>gcc y.tab.c lex.yy.c libfl.a -o first

fprintf() expects to get a file handle as its first argument. If you
meant to write to a file, you first need to open it with fopen() and put
the resulting pointer before the string in fprintf(). If (as I suspect
is more likely) you meant to write to standard output (i.e. the DOS
prompt), you want printf(), not fprintf().

Also, you have the wrong format specifier: "%d" is for signed integers,
not unsigned ones. You need to either change "%d" to "%u", or make
clausecount an int instead of an unsigned.
