+Fix build when iconv support is not available
+
+When iconv support is not available, the apr-util library does not
+provide character set conversion features, and therefore APR_HAS_XLATE
+is false.
+
+However, on Linux !defined(_WIN32) is always true, but the part of the
+code that defines the APRCharsetDecoder and APRCharsetEncoder are only
+enclosed in a #if APR_HAS_XLATE, without the "|| defined(_WIN32)"
+which leads to build failures: the APRCharsetEncoder and
+APRCharsetDecoder classes are used without being defined.
+
+This patch removes the || !defined(_WIN32) so that when iconv support
+is not here, we fall back to raising an exception at runtime.
