If you can't or won't spend time in fixing compline/d_gconvert.U ...
If I
can fix it, then I will undertake to do so.
At the moment, however, I have no idea how d_gconvert.U fits into "the scheme of things".
AFAICS, it's not part of the perl source.
... but I am always scared of interpolation when requiring quotes
I bothers me a bit, too.
Although the configure option that I used seems to have done the trick, it wasn't exactly noiseless:

Of course, I probably should at least run
make test before I start getting too excited about how successful it has been ;-)

Are you posting in the right place? Check out Where do I post X? to know for sure.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
-
Want more info? How to link
or How to display code and escape characters
are good places to start.
