对于 1994 年为 UNIX 编写的某些代码，我需要有一个 Windows 可执行文件。我试图从 cygwin 环境中做到这一点。从那时起，C++ 标准和标准库都发生了变化。
我尝试使用 -std= 和 -traditional-cpp 选项，但这些选项根本没有帮助我。我还发现 -fno-for-scope 和 -fno-operator-names 减少了错误的数量。从那时起，输入/输出库也发生了重大变化。我也认为从那时起预定义的（由预处理器）宏也有可能发生变化。
作者对代码的注释：

库中的 C 代码（库/linpack 和库/食谱）使用以下代码编译得很好：
gcc -c *.c
C++ 代码更成问题。../include 中有头文件，它们需要 -DANSI 来生成函数原型。它们没有extern "C"在标题中声明；它们正确包含在 C++ 源目录的标题中：
extern "C" {
#include "linpack.h"
}
所以，编译 A3dStream.C，我得到：
$ g++ -DANSI -I../include -c A3dStream.C

其他文件产生类似的错误集。
我在 Windows XP 下的 Cygwin 上使用 GCC 3.4.4。
我不是 C++ 大师——尽管我在软件考古方面做了相当多的工作——但在我看来，你需要更新代码以使用 C++ 标准头文件，因为 strstream.h 尤其缺失（所以，名义上，<strstream>改为使用），这意味着您必须处理std名称空间等。这段代码比标准早了 5 年，因此必须努力破解它以使其更新并不是没有道理的。
祝你好运！
I can think of two possibilities: AT&T offers both UWIN (which may be different enough from Cygwin to avoid the same trouble) and the source for old versions of CFront (which is probably the original compiler used).
Well, there's a third possibility, and I think it's the recommended action: edit the source and bring it up to date to the standard. If you intend to do any further development on this code, it's best to bite the bullet sooner rather than later.
You can still download the source for gcc 2.7.0 from the GNU web site.
You could download and make the older version of the compiler.
