--- Comment #7 from Jonathan Wakely <redi at gcc dot gnu.org> --- Author: redi Date: Sat Feb 9 00:40:31 2019 New Revision: 268714 URL: https://gcc.gnu.org/viewcvs?rev=268714&root=gcc&view=rev Log: PR libstdc++/88066 use <> for includes not "" Using #include "..." to include a header in the same directory fails if the user compiles with -I-, so always use something like <bits/...> for internal headers. I haven't added tests for this, because dg-options adds options to the end, and the position of -I- matters (if it's at the end then the tests won't find any headers in the build tree, as they're specified by -I options earlier in the flags). It's been manually tested though. PR libstdc++/88066 * include/bits/locale_conv.h: Use <> for includes not "". * include/ext/random: Likewise. * include/ext/vstring.h: Likewise.
