FWIW, I solved it this way in Guile, based on what GNU R does: http://git.sv.gnu.org/gitweb/?p=guile.git;a=commitdiff;h=7dc9ae7179b8b099897f8080b675e2a9c54d388c This is the very issue Simon mentioned here yesterday or so. Of course, not compiling in C99 mode solves the problem, and that would be a reasonable choice since most GNU projects that aim at maximum portability don't rely on C99 language features. Thanks, Ludovic.
