--- Comment #1 from Uroš Bizjak <ubizjak at gmail dot com> ---
This looks like a consequence of following i386-builtin-types.c comment:

# ??? Logically this should be intQI_type_node, but that maps to "signed char"
# which is a different type than "char" even if "char" is signed.  This must
# match the usage in emmintrin.h and changing this would change name mangling
# and so is not advisable.
DEF_PRIMITIVE_TYPE (QI, char_type_node)
