It was not deliberate. The current R build (R 2.6.0) was modified to use -std=gnu99 in the CC section for both architectures instead of using CFLAGS, that should solve the problem. A work around for older R is to set PKG_CFLAGS=-std=gnu99 when installing bnlearn. However, note that C99 compiler is not required for R so it may not be available. Since you don't really need any advanced functionality of C99, it may be a good idea to change it to a more portable C code. > Is it safe to force gcc to use C99 with either -std=c99 o -std=gnu99? > Not in your package as cannot assume gcc in general, but temporarily for R 2.5.1 on OS X, yes.
