+#### Unified HP-UX ANSI C configs.
+# Special notes:
+# - Originally we were optimizing at +O4 level. It should be noted
+#   that the only difference between +O3 and +O4 is global inter-
+#   procedural analysis. As it has to be performed during the link
+#   stage the compiler leaves behind certain pseudo-code in lib*.a
+#   which might be release or even patch level specific. Generating
+#   the machine code and analyzing the *whole* program appears to be
+#   *extremely* memory demanding while the performance gain is
+#   actually questionable. The situation is intensified by the default
+#   HP-UX data set size limit (infamous 'maxdsiz' tunable) of 64MB
+#   which is way too low for +O4. In other words, doesn't +O3 make
+#   more sense?
+# - Keep in mind that the compiler by default generates code suitable
+#   for execution on the host you're currently compiling at. If you
+#   intend to use it across various PA-RISC processors consider adding
+#   +Dportable.
+# - +DD64 is chosen in favour of +DA2.0W because it's ment to be
+#   compatible with *future* releases.
+# - If you run ./Configure hpux-parisc-[g]cc manually don't forget to
+#   pass -D_REENTRANT on HP-UX 10 and later.
+# - -DMD32_XARRAY triggers workaround for compiler bug we ran into in
+#   32-bit message digests. (For the moment of this writing) HP C
+#   doesn't seem to "digest" too many local variables (they make "him"
+#   chew forever:-). For more details look-up MD32_XARRAY comment in
+#   crypto/sha/sha_lcl.h.
