[committed] libstdc++: Initialize member in std::match_results [PR103549]
Commit Message
Tested powerpc64le-linux, pushed to trunk.
This fixes a -Wuninitialized warning for std::cmatch m1, m2; m1=m2;
Also name the template parameters in the forward declaration, to get rid
of the <template-parameter-1-1> noise in diagnostics.
libstdc++-v3/ChangeLog:
PR libstdc++/103549
* include/bits/regex.h (match_results): Give names to template
parameters in first declaration.
(match_results::_M_begin): Add default member-initializer.
