+ sigsegv, vma-iter: port to Solaris 10
+ On this platform, <sys/types.h> does not define off_t if neither
+ _LP64 nor _FILE_OFFSET_BITS is defined, which can happen if we
+ #undef _FILE_OFFSET_BITS. This became a problem with the new way
+ of doing stdbool, since config.h now includes <stdbool.h>, and
+ Solaris 10 <stdbool.h> includes <sys/feature_tests.h> which
+ arranges for _FILE_OFFSET_BITS to always be defined (if only to 32),
+ which <sys/types.h> assumes.
+ * lib/stackvma.c, lib/vma-iter.c (_FILE_OFFSET_BITS) [__sun && !_LP64]:
+ Define to 32 instead of leaving undefined.
