# For library symbols that can be defined in more than one header
# file, maps from symbol-name to legitimate header files.
# This list was generated via
# grep -R '__.*_defined' /usr/include | perl -nle 'm,/usr/include/([^:]*):#\s*\S+ __(.*)_defined, and print qq@ { "symbol": [ "$2", "public", "<$1>", "public"] },@' | sort -u
# I ignored all entries that only appeared once on the list (eg uint32_t).
# I then added in NULL, which according to [diff.null] C.2.2.3, can
# be defined in <clocale>, <cstddef>, <cstdio>, <cstdlib>,
# <cstring>, <ctime>, or <cwchar>. We also allow their C
# equivalents.
# In each case, I ordered them so <sys/types.h> was first, if it was
# an option for this type. That's the preferred #include all else
# equal. The same goes for <stdint.h>. The visibility on the
# symbol-name is ignored; by convention we always set it to private.
