Damn it, I just noticed that this option appeared in GCC 4.1.3 [0]. The
attached patch (applied to `master') fixes it (Simon: can you apply it
to other branches as well, if needed?).
What version of GCC are you using? Can you list all the compilation
options that are actually used when compiling things under `guile/src'?
BTW, is there any reason why GnuTLS is now compiled in C99 mode? It
doesn't seem to be explicitly set in `configure.in', so maybe some
Gnulib module requires it somehow?
Thanks for your help,
Ludovic.

The documentation also states that the actual "inline" semantic
change occurs starting with GCC 4.3.

Subject: [PATCH] Check whether `-fgnu89-inline' is supported before using it.
* configure.in: Check for `-fgnu89-inline', define Automake conditional
`HAVE_GCC_GNU89_INLINE_OPTION'.
* guile/src/Makefile.am (AM_CFLAGS): Only use `-fgnu89-inline' when
`HAVE_GCC_GNU89_INLINE_OPTION' is true.
