compiling this gives the following error: jitparser.y:15: error: ISO
C++
forbids declaration of ‘pair’ with no type
jitparser.y:15: error: expected ‘;’ before ‘<’ token
I want to include a pointer to an STL map entry, and
map<parameters>::iterator gives a similar error. Is there any way to
accomplish this.
BTW - removing the "const" before string removes this error, but
iterator is
pointer to a pair<const string, int> type.
