[sqlite] Comments in VDBE program

[Sairam Gaddam]

I am using C SQLite interface. How to enable comments in the VDBE program
here?
because they are not enabled by default.
gcc -DSQLITE -DEBUG filename.c ../sqlite3.c -ldl -lpthread
I tried with the above line in the terminal but could not succeed in
enabling the comments. Can any one help me with this?
I am using Linux 64 bit machine.
