<p dir="auto">A few days ago, in order to rebase a couple of my branches on an up-to-date master, I made a pull that forced me to rebuild my <code class="notranslate">deps</code> (maybe due to <a class="issue-link js-issue-link" data-error-text="Failed to load title" data-id="99107991" data-permission-text="Title is private" data-url="https://github.com/JuliaLang/julia/issues/12463" data-hovercard-type="pull_request" data-hovercard-url="/JuliaLang/julia/pull/12463/hovercard" href="https://github.com/JuliaLang/julia/pull/12463">#12463</a>?).</p>
<p dir="auto">Since then, though, I have not been able to rebuild gmp. It fails during config with text like this near the end:</p>

configure: error: Oops, mp_limb_t doesn't seem to work

<p dir="auto">I also get this error on a fresh clone.</p>
<p dir="auto"><del>Some googling suggests something about having absolute paths in the configure line breaks things.</del> If I go into the source directory and do a bare <code class="notranslate">./configure</code>, it succeeds (and gives a size of <code class="notranslate">mp_limb_t</code> of 8).</p>
<p dir="auto">Has anyone else seen this? I've looked a bit into how we might tweak the invocation of <code class="notranslate">configure</code> but the logic in <code class="notranslate">deps/Makefile</code> looks, um, complicated.</p>
