<pre>The line
double d = 0.4D;
causes clang to barf with
test.c:2:14: error: invalid suffix 'D' on floating constant
gcc accepts that code, and this seems to be the correct behavior at least for
C99+.
(see this gcc bug report from 10 years ago:
<a href="https://gcc.gnu.org/bugzilla/show_bug.cgi?id=39027">https://gcc.gnu.org/bugzilla/show_bug.cgi?id=39027</a>)</pre>
