--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
While compiling which file?
Is SIZEOF_INT and SIZEOF_LONG correctly defined in libcpp/config.h ?
Perhaps CHAR_BIT isn't defined?
Usually libcpp/ sources include "system.h" before including "cpplib.h" and
system.h has:
#if HAVE_LIMITS_H
# include <limits.h>
#endif
and so CHAR_BIT should be defined unless limits.h isn't present.
The cpplib.h part is:
#if CHAR_BIT * SIZEOF_INT >= 32
# define CPPCHAR_SIGNED_T int
#elif CHAR_BIT * SIZEOF_LONG >= 32
# define CPPCHAR_SIGNED_T long
#else
# error "Cannot find a least-32-bit signed integer type"
#endif
