<ul>
<li> <a name="index-Binary-notation"></a>
<a name="index-Notation_002c-binary"></a>
<small>FTANGLE</small> treats the construction ‘<samp>0b...</samp>’ as a binary notation
that it expands to an unsigned decimal number. Thus, ‘<samp>0b101</samp>’
expands to 5 and ‘<samp>0b1111111111111111</samp>’ expands to 65535.
</li><li> <small>FWEAVE</small> processes <b>typedef</b> statements during phase one, so they will
format properly even if they are used in a documentation part before
they are defined in a code part.
</li><li> The ‘<samp>-H</samp>’ option helps one to deal with identifiers defined in
header files. See <a href="_002dH_005f.html#g_t_002dH_005f">-H_</a>.
</li><li> <a name="index-Tags_002c-enum"></a>
<a name="index-Tags_002c-structure"></a>
Note that in C structure and enum tags do not define a new type, so the
tag name does not get highlighted in boldface, underlined in the index,
etc. (That is, if one says ‘<samp>struct S {...};</samp>’, one can’t say
‘<samp>S s;</samp>’, one must say ‘<samp>struct S s;</samp>’.) This is a good reason
for using C++, where such tags do define a new type.
