libstdc++: Avoid -Wparentheses warning with debug iterators
I noticed compiling e.g. std/ranges/adaptors/join.cc with
-D_GLIBCXX_DEBUG -Wsystem-headers -Wall gives the warning:
gcc/libstdc++-v3/include/debug/safe_iterator.h:477:9: warning: suggest parentheses around ‘&&’ within ‘||’ [-Wparentheses]
libstdc++-v3/ChangeLog:
* include/debug/safe_iterator.h (_GLIBCXX_DEBUG_VERIFY_OPERANDS):
Add parentheses to avoid -Wparentheses warning.
