+ * src/tr.c (PFI): Return `long', not `int'.
+ (PFL): Rename from PFI now that it returns long.
+ (squeeze_filter): Declare as `long': i, nr, out_len.

+
+ Tweak sort performance.
+
+ * src/sort.c (hard_LC_CTYPE): Remove.
+ (keylist): Renamed from keyhead. Now a pointer, not a
+ mostly-unused struct. All uses changed.
+ (findlines, keycompare, CMP_WITH_IGNORE, compare, checkfp, mergefps,
+ sort): Tune and use a more consistent style for reallocation.
+ (keycompare, main): Don't worry about LC_CTYPE;
+ it's buggy with multibyte chars anyway.
+ (compare): Invoke alloca (0) after each call to keycompare,
+ not just the ones that return nonzero. This avoids a memory
+ leak on architectures without builtin alloca that occurs
+ sometimes when a file contains all duplicate lines.
