GCC 4.4 related build problems: missing #include

<p>

C++ header dependencies <a href =
"http://www.cyrius.com/journal/gcc/gcc-4.3-include">got cleaned up in
GCC 4.3</a>, which broke a lot of code which relied on headers to be
included indirectly through some other headers.  I found some new build
failures with GCC 4.4 related to missing #includes; in particular,
<tt>#include &lt;cstdio&gt;</tt> is missing in a lot of code.

</p>

<p>

Typical errors look like these:

</p>

<pre>
error: 'sscanf' was not declared in this scope
error: 'EOF' was not declared in this scope
error: '::fseek' has not been declared
error: 'uint32_t' does not name a type
</pre>

<p>

Below is a table showing which header needs to be included for a number of
common functions:

</p>

<table>
<tr><td><b>Functions and defines</b></td><td><b>Header</b></td></tr>
<tr><td>fopen, fwrite, fclose</td><td>cstdio</td></tr>
<tr><td>fread, fseek, feof</td><td>cstdio</td></tr>
<tr><td>sscanf, sprintf</td><td>cstdio</td></tr>
<tr><td>rename, open</td><td>cstdio</td></tr>
<tr><td>EOF</td><td>cstdio</td></tr>
<tr><td>memset, memcpy, strdup</td><td>cstring</td></tr>
<tr><td>va_list</td><td>cstdarg</td></tr>
<tr><td>int16_t, uint32_t</td><td>stdint.h</td></tr>
</table>
