# Fix GCC 13 <cstdlib> — relibc declares but doesn't implement strtold (long double).
# GCC was built with _GLIBCXX_USE_C99_STDLIB=1 but relibc lacks the symbol.
# Remove 'using ::strtold' from the C++ stdlib header to prevent compile errors.

# Also remove stold() from basic_string.h which references std::strtold.
