U/WIN: final (for now) touches from John P. Linderman;

now we get 97% success rate, the remaining failures are
quite obscure.

+# __UWIN__ added so it could be used in ext/POSIX/POSIX.xs
+# to protect against either tzname definition.  According to Dave Korn
+
+#dgk gcc on uwin also predefined _UWIN as does the borland and digital
+#dgk mars compiler.
+#dgk
+#dgk Only ncc does not define _UWIN and this is intentional.  ncc is used
+#dgk to build binaries that do not require the uwin runtime.
+#dgk This could be used for building a native win32 perl using unix
+#dgk makefiles.  However, in this case you don't wan't _UWIN defined.
+#dgk
+#dgk I have used _UWIN everywhere else in any uwin specific changes.
+#dgk and _WIN32 on windows specific changes, and _MSVC on any compiler
+#dgk Visual C specific changes.  We also define _WINIX for any unix
+#dgk on windows implementation so that _UWIN or __cygwin__ imply _WINIX.
+
+# I left __UWIN__ as is, since I had already filed a patch,
+# and it might be useful to distinguish perl-specific tweaks
+# from generic uwin ones.

+# This from Dave Korn
+#dgk Windows splits shared libraries into two parts; the part used
+#dgk for linking and the part that is used for running.
+#dgk Given a library foo, then the part you link with is named
+#dgk  foo.lib
+#dgk and is in the lib directory.  The part that you run with
+#dgk is named
+#dgk  foo.dll or foo#.dll
+#dgk and is in the bin directory.  This way when you set you PATH
+#dgk variable, it automatically does the library search.
+#dgk
+#dgk Static libraries use libfoo.a.
+#dgk By the way if you specify -lfoo, then it will first look for foo.lib
+#dgk and then libfoo.a.  If you specify +lfoo, it will only look for
+#dgk static versions of the library.
+
+# So we use .lib as the extension, and put -lm in, because it is a .a
+# This probably accounts for the comment about dynamic libraries
+# needing work, and indeed, the build failed if I didn't undef it.

+# It likes to return an uppercase "disk" letter for the leading directory,
+# but your home directory may well have that in lower case.
+# In most cases, they are entirely interchangeable, but the perl tests
+# don't ignore case.  If they fail, change to the directory they expect.
