Thank you very much!

I've successfully builded gcc-core-4.1.2 and gcc-g++-4.1.2.You are right.The
reason is I used mingw's make, not cygwin's.

When building it I found an error in auto-generated file /gcc/configargs.h.If
having interest,copy the code below and compile it with gcc,see what the results
will be.

static const char configuration_arguments[] = "../gcc-4.1.2/configure
-prefix=/opt/gcc412
";

Unlike gcc when compiling with Vc7 it's OK.If you know why,please tell me.

After appending opt/bin to PATH,g++4.1.2 can work.

$ gcc -v
Using built-in specs.
Target: i686-pc-cygwin
Configured with: ../gcc-4.1.2/configure -prefix=/opt/gcc412
Thread model: single
gcc version 4.1.2

It seems include files and library's path have been set automaticly.
Where are the settings?I typed set to list all environment variables,but I
didn't see LIBRARY_PATH,C_INCLUDE_PATH and so on.

After building gcc,I wanted to build g++.but I didn't know how to build it
alone.So after unziping gcc-g++-4.1.2.tar.bz2 I used the configure file in
gcc-core-4.1.2.tar.bz2.Did the generated makefile rebuild gcc-core?
