Re: MLNLFFIGEN

Trying mlnlffigen with posix "regex.h" seems to work well, despite these
error messages:

    "/usr/include/bits/pthreadtypes.h":121.31-122.6: error: syntax
error: deleting  SEMICOLON RCURLY
    Likely cause: missing typedef declaration.

    "/usr/include/bits/pthreadtypes.h":125.3: error: syntax error:
inserting  RCURLY
    Likely cause: missing typedef declaration.


I failed with sqlite (www.sqlite.org), though. This is the command
line:

    mlnlffigen /usr/include/sqlite3.h

I got this (and no .sml files):

    "/usr/lib/gcc/i686-pc-linux-gnu/4.8.1/include/stdarg.h":40.73-90:
error: syntax error: replacing  ID with  TYPE_NAME
    Likely cause: missing typedef declaration.

    "/usr/lib/gcc/i686-pc-linux-gnu/4.8.1/include/stdarg.h":98.73-87:
error: syntax error: replacing  ID with  TYPE_NAME
    Likely cause: missing typedef declaration.

Now with "wchar.h" (again with no resulting .sml files):

    mlnlffigen /usr/include/wchar.h

    "/usr/lib/gcc/i686-pc-linux-gnu/4.8.1/include/stdarg.h":40.73-90:
error: syntax error: replacing  ID with  TYPE_NAME
    Likely cause: missing typedef declaration.
