guile-1.8 (1.8.7+1-3) FTBFS

[Thorsten Glaser <tg@mirbsd.de>]

Hi all,

how do I handle *this*? Is this a bug in the software (from reading
specs I would expect that guile is correct) or the headers (but how
does one specify padding if not so) or the compiler (GCC usually is
at fault, but guile wants -Werror and I think it’s not GCC’s)?

Maybe this only appears on m68k due to the unique aligning?

Anyway, I’m open for a suggestion how to proceed. Rob, I did
not file this in the BTS because I think some discussion about
what to file against ;-) may be needed first – if you want, we
can discuss that in the BTS too…

Quick workaround is _probably_ to disable -Werror for guile.

(FWIW, guile-1.8 is a build dependency of gnutls26 which is
why I’m building it.)
