+# anything except -D switches, and other sorts of compiler switches can
+# actively break things if Perl was compiled with a different compiler.
+# Moreover, although Perl likes to put stuff like -D_LARGEFILE_SOURCE and
+# -D_FILE_OFFSET_BITS=64 here, it would be fatal to try to compile PL/Perl
+# to a different libc ABI than core Postgres uses. The available information
+# says that all the symbols that affect Perl's own ABI begin with letters,
+# so it should be sufficient to adopt -D switches for symbols not beginning
+# with underscore.
+# For debugging purposes, let's have the configure output report the raw
+# ccflags value as well as the set of flags we chose to adopt.
