[ruby-list:50261] Haru Free PDF Library（ｌｉｂｈａｒｕ）の『ｈｐｄｆ.ｓｏ』ファイルのＭａｋｅ方法について

湧川と申します。

Haru　Free　PDF　Library（ｌｉｂｈａｒｕ）で『ｈｐｄｆ．ｓｏ』が作れずに困っております。
（Ｒｕｂｙ１．８．７の場合は、ネット上の『libharu_2_0_8_ruby_win32.zip』から『ｈｐｄｆ．ｓｏ』をコピーして使用しても
　問題ないのですが、バージョンＲｕｂｙ１．９以上になるとうまく動作しないので、最初からＭａｋｅすることにしました。）

【環境】
・Windows8.1（６４ｂｉｔ）
・Ｒｕｂｙ１．９．３−ｐ５５１（Ｒｕｂｙ　ｉｎｓｔａｌｌｅｒ）
・ｌｉｂｈａｒｕ−ＲＥＬＥＡＳＥ　２．３．０
・Ｖｉｓｕａｌ　Ｓｔｕｄｉｏ　２０１３　Ｅｘｐｒｅｓｓ　Ｄｅｓｋｔｏｐ

ＶＳ２０１３を使って、『ｌｉｂｈｐｄｆ．ｄｌｌ』をＭａｋｅ（ｎｍａｋｅ）し、Ｃ＃用のｄｅｍｏプログラムでＰＤＦを問題なく作成することはできました。
しかし、Ｒｕｂｙ用の『ｈｐｄ．ｓｏ』ファイルを、ｅｘｅｔｃｏｎｆ．ｒｂ⇒Ｍａｋｅファイルを作成⇒Ｍａｋｅ（ｎｍａｋｅ）すると下記のエラー

C:\libharu-RELEASE_2_3_0\if\ruby>ruby extconf.rb
creating Makefile
C:\libharu-RELEASE_2_3_0\if\ruby>nmake
makefile(82) : fatal error U1000: 構文エラー : マクロ呼び出しに ')' がありません。
Stop.

同様に、Ｒｕｂｙ２．０／２．１／２．２とバージョンを変えてみても同じ結果です。
また、Ｃｙｇｗｉｎ環境でＲｕｂｙやｌｉｂｈａｒｕをソースコードからコンパイルしてもうまくいきません。
extconf.rbやMakefile側ではなく多分当方の手順等に間違いがあると思うのですが、ネット検索しても
解決策が見つからず行き詰っております。
どなたかおわかりの方がいらっしゃいましたら、教えて下さい。

よろしくお願いします！


長くなりますが、extconf.rbとMakefileのリストを添付します。
