+# Unix aware build tools may provide (e.g. pkg-config) and accept
+# (e.g. gcc) the -lNAME linker option.  While they create libNAME.so
+# as the import library, they may be unaware of the additional dll.
+# The dllhelper wrappers take care of copying the real dll when
+# copying the libNAME.so.
+#
+# Cygwin and MinGW aware build tools may create the import library
+# as libNAME.dll.a or libNAME.dll.lib, and are aware of the dll,
+# while a subsequent linker step still receives the -lNAME option.
+#
+# MSVC aware build tools may provide (e.g. icu-config) and accept
+# (e.g. cl.exe) the NAME.lib linker option, maybe with full path,
+# and are aware of the dll.
+#
+# Libtool does accept both the Unix and MSVC variants now, but does
+# search for the libNAME(.la|.dll|.so|.a) file upon -lNAME, in order.
+#
+# As Gentoo ebuilds may remove libNAME.la, we need the libNAME.so
+# because we don't want to have libNAME.dll as an import library.
+#
+# The static library may be created as libNAME.a, libNAME.lib or even
+# NAME.lib - the latter we need to check for static or import library.
+#
+# For whatever import library file we find, make sure there is both the
+# NAME.lib and the libNAME.so for dynamic linkability via all the
+# -lNAME, the NAME.lib and the libNAME.so linker option.
