Hello,
I get warnings compiling my own C89 project that uses C99 check.h.

If 'check' program is installed in the default path, when I compile my project
:
$ make
gcc -ansi -Wall -W -pedantic -Wmain -Wextra -Wwrite-strings -Wstrict-prototypes
-Wno-missing-braces -Wswitch -Wswitch-default -Wswitch-enum -Wfloat-equal -s
-O2
-c ../arbre.c
gcc -ansi -Wall -W -pedantic -Wmain -Wextra -Wwrite-strings -Wstrict-prototypes
-Wno-missing-braces -Wswitch -Wswitch-default -Wswitch-enum -Wfloat-equal -s
-O2
-lcheck check_arbre.c arbre.o -o check_arbre
gcc -ansi -Wall -W -pedantic -Wmain -Wextra -Wwrite-strings -Wstrict-prototypes
-Wno-missing-braces -Wswitch -Wswitch-default -Wswitch-enum -Wfloat-equal -s
-O2
-c ../sequence.c
gcc -ansi -Wall -W -pedantic -Wmain -Wextra -Wwrite-strings -Wstrict-prototypes
-Wno-missing-braces -Wswitch -Wswitch-default -Wswitch-enum -Wfloat-equal -s
-O2
-c ../liste.c
gcc -ansi -Wall -W -pedantic -Wmain -Wextra -Wwrite-strings -Wstrict-prototypes
-Wno-missing-braces -Wswitch -Wswitch-default -Wswitch-enum -Wfloat-equal -s
-O2
-lcheck check_sequence.c sequence.o arbre.o liste.o -o check_sequence
gcc -ansi -Wall -W -pedantic -Wmain -Wextra -Wwrite-strings -Wstrict-prototypes
-Wno-missing-braces -Wswitch -Wswitch-default -Wswitch-enum -Wfloat-equal -s
-O2
-lcheck check_liste.c liste.o arbre.o -o check_liste

In the second case ('check' program installed in '/tmp/logiciel-check-0.9.6') :
In this case, I use the correct environment variables :
$export LD_LIBRARY_PATH="/tmp/logiciel-check-0.9.6/usr/lib:${LD_LIBRARY_PATH}"
$export LIBRARY_PATH="/tmp/logiciel-check-0.9.6/usr/lib:${LIBRARY_PATH}"
$export CPATH="/tmp/logiciel-check-0.9.6/usr/include:${CPATH}"
and because I am french I add :
$export LANG=en_GB.UTF-8

$ make
gcc -ansi -Wall -W -pedantic -Wmain -Wextra -Wwrite-strings -Wstrict-prototypes
-Wno-missing-braces -Wswitch -Wswitch-default -Wswitch-enum -Wfloat-equal -s
-O2
-c ../arbre.c
gcc -ansi -Wall -W -pedantic -Wmain -Wextra -Wwrite-strings -Wstrict-prototypes
-Wno-missing-braces -Wswitch -Wswitch-default -Wswitch-enum -Wfloat-equal -s
-O2
-lcheck check_arbre.c arbre.o -o check_arbre

Do you understand why the warnings ARE in one case and ARN'T in the other?
Thank you.

------- Comment #1 from pinskia at gcc dot gnu dot org  2009-03-05 20:08 -------
This is because if the header is installed in the system includes directory GCC
does not warn about extensions.

If you want to have /tmp/logiciel-check-0.9.6/usr/include in the system include
directories use -isystem.
