csc.exeのチェックでNoになる件

    dnl Check csc.exe
    AC_PATH_PROG(CSC_PATH, csc.exe)
    if test -n "$CSC_PATH";then
        CSC_PATH=`dirname "$CSC_PATH"`
    fi
    if test -n "$with_csc_path";then
        with_csc_path=`cygpath -u "$with_csc_path"`
    fi
    if test -x "$with_csc_path/csc.exe"; then
        CSC_PATH="$with_csc_path"
    else
       csctest=`./oowintool --csc-compilerdir`;
       if test -x "$csctest/csc.exe"; then
           CSC_PATH="$csctest"
       fi
    fi
    if test ! -x "$CSC_PATH/csc.exe"; then
        AC_MSG_ERROR([csc.exe not found. Make sure it's in the path or use --with-csc-path])
    fi
    # Convert to posix path with 8.3 filename restrictions ( No spaces )
    CSC_PATH=`cygpath -d "$CSC_PATH"`
    CSC_PATH=`cygpath -u "$CSC_PATH"`

csc.exeのチェックがnoになるのが気になったので少し見てみてみたけど。AC_PATH_PROG(CSC_PATH, csc.exe)でnoが返ってる。
