title: sql.h header file missing though unixODBC is installed
body: <p>I am on an up-to-date Ubuntu 12.04 system. I have unixodbc (v2.2.14 from ubuntu repos), MySQL and its relevant drivers installed. Also connected to a valid DSN. Verified by issuing <code>isql DBName UName passwd</code>.</p>
  
  <p>I am trying to compile a C application that interacts with the database using ODBC. Almost everywhere I searched seemed to indicate that I should have "sql.h" installed somewhere. A <code>find / -iname sql.h -print</code> showed I don't have it.</p>
  
  <p>So my question is: where is it? Did something go wrong with the install (no errors were reported though)? And what steps do you recommend? Reinstallation? Compilation from source code (the latest version?)?</p>
