Thanks.  I get the following warning when compiling regex.c:

  regex.c:516:0: warning: macro "STREQ" is not used [-Wunused-macros]
   #define STREQ(s1, s2) ((strcmp (s1, s2) == 0))
   ^

When compiling the test suite, I get this warning:

Compiling src/regex-tests.el

  In toplevel form:
  src/regex-tests.el:416:1:Warning: Unused lexical variable `newline'
