VC6.0的一个编译错误：fatal error C1001: INTERNAL COMPILER ERROR。
最近在编译一个VC6.0工程(开发环境:win2000+VS6.0+Sp6)，在加入预编译头后出现了下面的编译错误提示：
c:/program files/microsoft visual studio/vc98/include/xlocnum(106) :
fatal error C1001: INTERNAL COMPILER ERROR
(compiler file 'msc1.cpp', line 1794)
Please choose the Technical Support command on the Visual C++
Help menu, or open the Technical Support help file for more information
Error executing cl.exe.
工程中的每个cpp文件编译都没有问题（除了预编译头对应的cpp文件），很是奇怪，于是在网上找了一下，找到下面一种解决办法：
VC6.0的一个编译错误的解决
在window98下使用vc6.0时，如果预编译头文件(stdafx.h)中包含了模板类的头文件，比如atl的头文件时，编译器会报错：
fatal error C1001: INTERNAL COMPILER ERROR
(compiler file 'msc1.cpp', line 1786)
造成这种问题的原因是编译器分配的内存超过了限制。
解决的办法有三种：
1.给编译器增大内存限制。在project（工程）->setting（设置）->c/c++的project option（工程选项）中，添加/Zm#nn选项，#nn是一个数字，取值最大为2000。默认为100。但是这种方法好像没有什么用处。
2.将模板类头文件从stdafx.h中移出；
3.不使用预编译头文件。project->setting->c/c++，选择所有的.cpp文件，都使用“不使用预编译头文件“的选项。缺点是编译的时候很慢。

还有一个英文的：
I see that while compiling ITEL.CPP it is trying and failing to open
Debug/IODIARY.PCH. I also see that there is no IODIARY.CPP. Exactly how is
IODIARY.PCH supposed to be created?
Turn off precompiled headers for all files in the project, and rebuild. If
the build still fails, then... uh-oh..
Modify the project to use the default STDAFX.CPP/STDAFX.H method of using
PCH. Then, add an empty file STDAFX.H and an empty file STDAFX.CPP to the
project. Then, for each .CPP file, add as the first line #include
"stdafx.h" . Then compile. This should work. If it does not... uh-oh.
In order for pre-compiled headers to work properly each .CPP must have as
its first #include statement the name of the one .H (such as STDAFX.H) that
includes all the "actual" .H's (windows.h, stdio.h, etc.) that should be
included by ALL .CPPs.
That is the important part. You don't usually want EVERYsingle .H that is
included in ANY .CPP in the project to be in STDAFX.H -- you do normally
want windows.h, because it is the big one that can include a lot and is
usually included in every .CPP. Putting just windows.h in stdafx.h (and
removing it from all the .CPPs) can speed up the build tremendously.

在MSDN中搜索到这种错误相关主题：

后来把预编译去掉后，Build终于通过了运行了，可这也太慢了，郁闷中……
还不知有没更好的解决办法？？同样的工程放在VC++.net2003中却编译顺利通过,运行正常.!!!!
