Is this something that should be fixed in LilyPond?

I think so, yes (especially since ‘scm_internal_hash_fold’ was intended
to be sort-of internal.)

For reference, I'm fairly certain this build failure was introduced
with Guile commit a07010bf1828704edd9a40cadb0eaf820b8f3638.

Yes, that’s the one.

If I add the typedefs to the appropriate LilyPond header file and use
them, the problem goes away, but I don't know if there are unexpected
side effects of this.

I think you want a fix that retains compatibility with 1.8.  How about
having a ‘configure’ test checking for this typedef?

I am unable to test any further, because there are more build failures
down the pipeline.  :-)

Heh.  Let us know what other Guile-related failures you stumble upon!

I patched the Lilypond header files and code calling them to get round the above problem, but then hit this one:

Code like this which dynamically declares procedures,and works fine in V1.8.7 but barfs with V1.9.9

;;; This is OK
(define-public PLATFORM
    (car (string-tokenize (utsname:sysname (uname)))))))

;;; This is OK

;;; This fails, but works in 1.8.7
   (define native-getcwd

   (define (slashify x)
     (if (string-index x #\\)
          "//*" "/"
          (string-regexp-substitute "\\\\" "/" x))))

   (define-public (ly-getcwd)
     (slashify (native-getcwd))))

   (define-public ly-getcwd
