In ANSI C, this is correct although rarely used like that.
I suppose it is followed by a line that ends with a semicolon.
Look at the K&R syntax in BNF here:
http://www.cs.man.ac.uk/~pjj/bnf/c_syntax.k_r
stat : id ':' stat
| 'case' const_exp ':' stat
| 'default' ':' stat
| exp? ';'
| compound_stat
| 'if' '(' exp ')' stat
| 'if' '(' exp ')' stat 'else' stat
| 'switch' '(' exp ')' stat
| 'while' '(' exp ')' stat
| 'do' stat 'while' '(' exp ')' ';'
| 'for' '(' exp? ';' exp? ';' exp? ')' stat
| 'goto' id ';'
| 'continue' ';'
| 'break' ';'
| 'return' exp? ';'
exp : assignement_exp ( ',' assignment_exp )*
So a statement (stat) must end with ';', it can be an expression (exp)
that is a list of assignement_exp separated by ','.
No bug in the generated code but subject to discussions, so wrong :)
Cheers,
Thierry
