Both svn and httpd are written in C, not in C++.  I would expect C++
stdlibs to not be required for C projects. (but perhaps on your system
svn gets compiled as C++ code, for some reason)

If this is the problem, it would affect all httpd modules, not just
mod_*_svn.  Are you able to compile, link, and load (with LoadModule)
a Hello World httpd module in your environment?

Hello all,
For linking to shared libraries, is "libstdc++.so" required in gcc. 
My install path only shows :
~:/opt/freeware/lib/gcc/powerpc-ibm-aix6.1.0.0/4.8.3 -->
$ ls
include  libstdc++.a  libstdc++.a-gdb.py  ppc64  pthread
just the static library. 
Could this be why mod_dav_svn.so cannot be built?
Thanks,
Anselm

Here is an old email that suggests which linker flags are needed to create .so, 
rather than .a, shared libraries:

https://gcc.gnu.org/ml/gcc-help/2002-05/msg00065.html

Perhaps edit your Makefile and add -Wl,-G to the end of the LINK_APACHE_MOD 
line.

svn status merges intersected external records into single row

Here is the batch script for the windows:

```
@echo off

set REPODIR=test_repo
set "REPOROOT=%~dp0%REPODIR%"
set "REPOURL=file:///%REPOROOT:\=/%"
set WCROOT=%REPODIR%_root

if exist "%REPOROOT%\" rmdir /S /Q "%REPOROOT%"
if exist "%WCROOT%\" rmdir /S /Q "%WCROOT%"

mkdir "%REPOROOT%"
svnadmin create "%REPOROOT%"
mkdir "%WCROOT%"

svn co "%REPOURL%" "%WCROOT%"

rem creating tree w/o externals
mkdir "%WCROOT%/dir1/dir1_subdir1" || goto :EOF
mkdir "%WCROOT%/dir1/dir1_subdir2" || goto :EOF
mkdir "%WCROOT%/dir2/dir2_subdir1" || goto :EOF
mkdir "%WCROOT%/dir2/dir2_subdir2" || goto :EOF

svn add "%WCROOT%/*.*" || goto :EOF

svn ci "%WCROOT%" -m "rev1" || goto :EOF

rem update to the head
svn up "%WCROOT%" || goto :EOF

rem creating externals
type nul > "$externals.txt"

(
  echo.^^/dir1/dir1_subdir1 ext/dir1_subdir1
  echo.^^/dir1/dir1_subdir2 ext/dir1_subdir2
  echo.^^/dir2/dir2_subdir1 dir2_subdir1
  echo.^^/dir2/dir2_subdir2 dir2_subdir2
) >> "$externals.txt"

svn pset svn:externals -F "$externals.txt" "%WCROOT%" || goto :EOF

svn ci "%WCROOT%" -m "rev2" || goto :EOF

rem update to the head
svn up "%WCROOT%" || goto :EOF

rem show status
svn status "%WCROOT%"
```

The output:

The externals list is:

```

X   test_repo_root\dir2_subdir2
X   test_repo_root\ext
```

instead of:

```
X   test_repo_root\dir2_subdir1
X   test_repo_root\dir2_subdir2
X   test_repo_root\ext\dir1_subdir1
X   test_repo_root\ext\dir1_subdir2
```

This forces to use `svn pget svn:externals` + `a parser` instead of `svn  
status` + `a filter` in scripting to extract the records set.
