+* 'make test' fails in BN_sqr [commonly with "error 139" denoting SIGSEGV]
+ if elder GNU binutils were deployed to link shared libcrypto.so.
+
+As subject suggests the failure is caused by a bug in elder binutils,
+either as or ld, and was observed on FreeBSD and Linux. There are two
+options. First is naturally to upgrade binutils, the second one - to
+reconfigure with additional no-sse2 [or 386] option passed to ./config.
+
+* If configured with ./config no-dso, toolkit still gets linked with -ldl,
+ which most notably poses a problem when linking with dietlibc.
+
+We don't have framework to associate -ldl with no-dso, therefore the only
+way is to edit Makefile right after ./config no-dso and remove -ldl from
+EX_LIBS line.
