stdio.h not found when building Ada or Obj-C++ front ends under MinGW

[Wolfgang.Boiger@gmx.net]

Hi everyone,

I'm trying to build gcc 4.1.1 under MinGW. When building with "--enable-languages=c,c++,ada" or "--enable-languages=c,obj-c++" a problem occurs which I can't solve.

Here is a detailed report of what happens:

* Started with: German Win2kSP4
  (never touched by MinGW & Co before)
* Execute MinGW-5.0.3.exe, which installs previously
  downloaded files to "C:\MinGW":
    * binutils-2.15.91-20040904-1.tar.gz
    * gcc-ada-3.4.2-20040916-1.tar.gz
    * gcc-core-3.4.2-20040916-1.tar.gz
    * gcc-g++-3.4.2-20040916-1.tar.gz
    * gcc-g77-3.4.2-20040916-1.tar.gz
    * gcc-java-3.4.2-20040916-1.tar.gz
    * gcc-objc-3.4.2-20040916-1.tar.gz
    * mingw32-make-3.80.0-3.tar.gz
    * mingw-runtime-3.11.tar.gz
    * w32api-3.8.tar.gz
* Execute MSys-1.0.10.exe, which installs itself into
  "C:\msys\1.0".
* Start MSYS

Then I execute the following commands at the MSYS prompt:
$ tar xjvf gcc-4.1.1.tar.bz2
$ cd gcc-4.1.1
$ ./configure  --prefix=/mingw  --host=pentium-pc-mingw32
    --target=i386-pc-mingw32  --program-prefix=""
    --with-as=/mingw/bin/as.exe  --with-ld=/mingw/bin/ld.exe
    --with-gcc  --with-gnu-ld  --with-gnu-as  --enable-threads
    --disable-nls  --enable-languages=c,ada
    --disable-win32-registry  --disable-shared  --without-x
    --enable-interpreter  --enable-hash-synchronization
    --enable-libstdcxx-debug
$ make
(The $ denotes the MSYS prompt. The configure command is one line and comes from Scott Meyers new guide.)

Running the make command gives a lot of output, which ends up in the following lines:

Replacing ada by obj-c++ yields exactly the same error, building only the c frontend works without problems.

I found other problem reports (http://gcc.gnu.org/ml/gcc-help/2006-04/msg00026.html and http://gcc.gnu.org/ml/gcc-help/2003-01/msg00114.html) which also deal with the missing stdio.h, but the problem there seems to be the cross compiling (As far as I understand: I am not cross compiling here). Is it possible to build the ada and/or obj-c++ frontends in MinGW?

By the way, "./config.guess" in gcc-directory gives "i686-pc-mingw32".

Thanks for your help in advance,
sorry for my crappy english.
