SQLite

There's no problem.
I would like to propose inlining of several pretty often used functions:
 sqlite3BtreeGetPageSize
 sqlite3BtreePager
 sqlite3PagerBackupPtr
 sqlite3PagerRef
 sqlite3PagerPageRefcount
 sqlite3PagerGetData
 sqlite3PagerGetExtra
 sqlite3PagerIsreadonly
 sqlite3PagerRefcount
 sqlite3PagerFilename
 sqlite3PagerVfs
 sqlite3PagerFile
 sqlite3PagerJournalname
 sqlite3PagerNosync
 sqlite3PagerTempSpace
 sqlite3PagerIsMemdb
For instance, I introduced a compiler flag named INLDEF and for each ot these functions I issued:
in the declaration section:

<verbatim>
    #ifdef INLDEF
    # define sqlite3BtreeGetPageSize(a) (a)->pBt->pageSize
    #else//INLDEF
    SQLITE_PRIVATE INL int sqlite3BtreeGetPageSize(Btree*);
    #endif//INLDEF
</verbatim>

and in the implementation section: 

<verbatim>
    #ifndef INLDEF
    SQLITE_PRIVATE int sqlite3BtreeGetPageSize(Btree *p){
      return p->pBt->pageSize;
    }
    #endif//INLDEF
</verbatim>

Modern C compilers do this kind of inlining automatically.  There is no need
to complicate the code.
