      Perhahs, I have a concept problem. If you have a c++ template in a ".h" 
file without a ".c" file and you compile it you should obtain a .o object. I 
do not need any “.gch” file

So this happens with the 3.2.3 version.

sun1:~/test> g++ -v
Reading specs from /usr/local/gcc-3.2.3/bin/../lib/gcc-lib/sparc-sun-
solaris2.9/3.2.3/specs
Configured with: ./configure --prefix=/usr/users/afernand/comp/gcc-3.2.3 -
enable-language=c,c++
Thread model: posix
gcc version 3.2.3

sun1:~/test> ls -la test*
-rw-r-----   1 cmarco   indra        141 Mar  3 16:49 test.h
sun1:~/test> g++ -m64 -x c++ -c test.h
sun1:~/test> ls -la test*
-rw-r-----   1 cmarco   indra        141 Mar  3 16:49 test.h
-rw-r-----   1 cmarco   indra        672 Mar 17 09:18 test.o

Now if I use the 3.4.4 version: 

sun1:~/test> g++ -v
Reading specs from /usr/local/gcc-34/bin/../lib/gcc/sparc-sun-
solaris2.9/3.4.4/specs
Configured with: ./configure --prefix=/usr/users/afernand/comp/gcc-bootstrap-

-enable-language=c --without-headers --disable-shared :

-enable-language=c --without-headers --disable-shared :

language=c,c++
Thread model: posix
gcc version 3.4.4 20041222 (prerelease)
 
sun1:~/test> ls -la test*
-rw-r-----   1 cmarco   indra        141 Mar  3 16:49 test.h 
sun1:~/test>  g++ -m64 -x c++ -c test.h
sun1:~/test> ls -la test*
-rw-r-----   1 cmarco   indra        141 Mar  3 16:49 test.h
-rw-r-----   1 cmarco   indra    1034879 Mar 17 09:23 test.h.gch

Something have change. ¿Should I have use other options?
