Exnode_t* exexpr(Expr_t*, const char*, Exid_t*, int);
Exnode_t* excast(Expr_t*, Exnode_t*, int, Exnode_t*, int);
Exnode_t* exnewnode(Expr_t*, int, int, int, Exnode_t*, Exnode_t*);
void exfreenode(Expr_t*, Exnode_t*);
int expush(Expr_t*, const char*, int, const char*, Sfio_t*);
int expop(Expr_t*);
int excomp(Expr_t*, const char*, int, const char*, Sfio_t*);

char* extype(int);
Extype_t exzero(int);
DESCRIPTION
exopen() is the first function called. exclose() is the last function
called. exccopen() is the called if code generation will be used.
exccclose() releases the state information allocated in exccopen().
exstatement() saves statement start information. exrewind() restores
statement start information saved by exstatement().
