library support.
-The workaround may be to change the following lines in apps/Makefile.ssl and
-test/Makefile.ssl:

* Parallell make leads to errors
The solution is simple for now: don't run parallell make when testing.

-According to a problem report, there are bugs in gcc 3.0 that are

-PEM_get_EVP_CIPHER_INFO(). The triggering code is the following:

+- According to multiple problem reports, some of our message digest

+ "falls between" OpenSSL [0.9.8 and later], Solaris ld and GCC. The bug

* solaris64-sparcv9-cc SHA-1 performance with WorkShop 6 compiler.
Workaround: modify the target to +O2 when building with no-asm.
-* Poor support for AIX shared builds.
-
-do_aix-shared rule is not flexible enough to parameterize through a
-config-line. './Configure aix43-cc shared' is working, but not
-'./Configure aix64-gcc shared'. In latter case make fails to create shared
-libraries. It's possible to build 64-bit shared libraries by running
-'env OBJECT_MODE=64 make', but we need more elegant solution. Preferably one
-supporting even gcc shared builds. See RT#463 for background information.

with gcc 2.95.3
appreciated.
NOTE: building non-shared doesn't come with this problem.
+
+* ULTRIX build fails with shell errors, such as "bad substitution"
+ and "test: argument expected"
+
+The problem is caused by ULTRIX /bin/sh supporting only original
+Bourne shell syntax/semantics, and the trouble is that the vast
+majority is so accustomed to more modern syntax, that very few
+people [if any] would recognize the ancient syntax even as valid.
+This inevitably results in non-trivial scripts breaking on ULTRIX,
+and OpenSSL isn't an exclusion. Fortunately there is workaround,
+hire /bin/ksh to do the job /bin/sh fails to do.
+
+1. Trick make(1) to use /bin/ksh by setting up following environ-
+ ment variables *prior* you execute ./Configure and make:
+
+ PROG_ENV=POSIX
+ MAKESHELL=/bin/ksh
+ export PROG_ENV MAKESHELL
+
+ or if your shell is csh-compatible:
+
+ setenv PROG_ENV POSIX
+ setenv MAKESHELL /bin/ksh
+
+2. Trick /bin/sh to use alternative expression evaluator. Create
+ following 'test' script for example in /tmp:
+
+ #!/bin/ksh
+ ${0##*/} "$@"
+
+ Then 'chmod a+x /tmp/test; ln /tmp/test /tmp/[' and *prepend*
+ your $PATH with chosen location, e.g. PATH=/tmp:$PATH. Alter-
+ natively just replace system /bin/test and /bin/[ with the
+ above script.
+
+* hpux64-ia64-cc fails blowfish test.
+
+Compiler bug, presumably at particular patch level. It should be noted
+that same compiler generates correct 32-bit code, a.k.a. hpux-ia64-cc
+target. Drop optimization level to +O2 when compiling 64-bit bf_skey.o.
+
+* no-engines generates errors.
+
+Unfortunately, the 'no-engines' configuration option currently doesn't
+work properly. Use 'no-hw' and you'll will at least get no hardware
+support. We'll see how we fix that on OpenSSL versions past 0.9.8.
+
+* '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.
