[Bug driver/14601] New: MinGW/MSYS bootstrapped compiler doesn't work

[stl at caltech dot edu]

I currently use MinGW gcc 3.3 crossed over from i686-pc-linux-gnu. It lives in 
C:\MinGW. If I compile a Hello World program with g++ -v, it says (in part):

ignoring nonexistent directory "C:/MinGW/mingw32/include"
ignoring nonexistent directory "/home/stl/temp/dest/include/c++/3.3"

#include <...> search starts here:

 C:/MinGW/lib/gcc-lib/mingw32/3.3/include
End of search list.

It produces a hello.exe that works.

I bootstrapped 3.3.3 in MinGW/MSYS. I put it in C:\Temp\gcc\gcc-3.3.3-meow. It 
says:

ignoring nonexistent directory "c:/temp/gcc/dest/include/c++/3.3.3"
ignoring nonexistent directory "c:/temp/gcc/dest/include/c++/3.3.3/i686-pc-

End of search list.

It then fails to find <iostream>.

All of the MinGW/MSYS bootstrapped gcc's I've been accumulating - 3.3, 3.3.1, 
3.3.3, and 3.4-20040310 with the PR12974 and PR14291 patches - have this same 
problem.

Interestingly, compiling hello.c using stdio.h with gcc 3.3.3 worked. I don't 
know why.

Is this a problem with gcc? Am I not configuring my bootstraps properly? Since 
I can cross a compiler over and then move it to any old directory (i.e. 
C:\MinGW) I like, I figure that I should be able to bootstrap with a 
destination of C:\Temp\gcc\dest and then move it to any old directory.

This is how I configured 3.3 during the cross:

Reading specs from C:/MinGW/bin/../lib/gcc-lib/mingw32/3.3/specs
Configured with: /home/stl/temp/src/configure --prefix=/home/stl/temp/dest --
build=i686-pc-linux-gnu --host=mingw32 --ta
rget=mingw32 --enable-languages=c,c++ --with-gcc --with-gnu-as --with-gnu-ld --

red --enable-sjlj-exceptions --disable-debug --without-newlib
Thread model: win32
gcc version 3.3 (mingw special 20030514-1)

This is how I configured the 3.3.3 bootstrap:

Using built-in specs.
