Thanks for creating the issue (STDCXX-737)! I think I've figured out
the problem with the original patch. Please check to make sure things
work as you expect with the change I'm suggesting in my comment on
the issue and if you're happy with it go ahead and commit the new

Hi Farid,
This change seems to have broken the config test dependency
detection logic and caused the EDG eccp build regression
described in STDCXX-733.
I assigned the issue to you but just in case you miss it
among all the other traffic on [EMAIL PROTECTED] Can you please
take a look into it whenever you have chance?

Incidentally, out of curiosity, what is this change supposed to do?
I made this change in GNUmakefile because the
EXTERN_FUNCTION_TEMPLATE.cpp
config test has compiled twice on my gcc/Linux:
1) first it was not linked with extern_function_template_imp.o and due
to this
the macro _RWSTD_NO_EXTERN_FUNCTION_TEMPLATE is defined in config.h
config.log:
---------
...
gcc -D_RWSTDDEBUG -pthread -I. -pedantic -nostdinc++ -g -W -Wall
-Wcast-qual -Winline -Wshadow -Wwrite-strings -Wno-long-long
-Wcast-align -c
/usr/src/trunk/etc/config/src/extern_function_template_imp.cpp -o
extern_function_template_imp.o
gcc -D_RWSTDDEBUG -pthread -I. -pedantic -nostdinc++ -g -W -Wall
-Wcast-qual -Winline -Wshadow -Wwrite-strings -Wno-long-long
-Wcast-align -c
/usr/src/trunk/etc/config/src/EXTERN_FUNCTION_TEMPLATE.cpp -o
EXTERN_FUNCTION_TEMPLATE.o
gcc EXTERN_FUNCTION_TEMPLATE.o -pthread -lm -lsupc++ -o
EXTERN_FUNCTION_TEMPLATE
EXTERN_FUNCTION_TEMPLATE.o(.text+0x26): In function `main':
/usr/src/trunk/etc/config/src/EXTERN_FUNCTION_TEMPLATE.cpp:47: undefined
reference to `S<int> foobar<int>(S<int>)'
collect2: ld returned 1 exit status
...
---------
config.h:
---------
...
// #define _RWSTD_NO_extern_function_template_imp
#define _RWSTD_NO_EXTERN_FUNCTION_TEMPLATE
...
---------
2) second it was linked with extern_function_template_imp.o and the
config.h contains the second entry, where
_RWSTD_NO_EXTERN_FUNCTION_TEMPLATE define is commented
config.log:
---------
...gcc -D_RWSTDDEBUG -pthread -I. -pedantic -nostdinc++ -g -W -Wall
-Wcast-qual -Winline -Wshadow -Wwrite-strings -Wno-long-long
-Wcast-align -c
/usr/src/trunk/etc/config/src/EXTERN_FUNCTION_TEMPLATE.cpp -o
EXTERN_FUNCTION_TEMPLATE.o
gcc EXTERN_FUNCTION_TEMPLATE.o -pthread extern_function_template_imp.o
-lm -lsupc++ -o EXTERN_FUNCTION_TEMPLATE
./EXTERN_FUNCTION_TEMPLATE
...
---------
config.h:
---------
...
// #define _RWSTD_NO_EXTERN_FUNCTION_TEMPLATE
...
---------
As a result the _RWSTD_NO_EXTERN_FUNCTION_TEMPLATE macro is defined
while gcc supports the extern function templates.
The first compilation is come from "%.o: %.cpp" rule, and the second -
from "config:" rule.
Farid.
