Sorry, missed the previous mail.

My report may have been a little cryptic: "> t.h" meant I created an empty 
.h-file.  I must admit it would have been clearer also to add invalid 
content to t2.cpp.  
I am now using gcc 3.3.  I have an empty t.h, and t2.cpp contains:
"int main() { bla };"

Trying to compile "gcc -o test t.h t2.cpp" shows that it first comes to 
the constatation that t.h is a header file and thus compilation should 
fail, but still then tries to compile t2.cpp, and fails afterwards.  
It doesn't make a lot of difference in this small example, but when you 
have a very large t2.cpp with a couple of more errors, compilation will 
take a long time before the inevitable failure, and a lot of 
compilation error messages will appear obfuscating the real origin of the 
failure.

This might not even be considered as a bug by the gcc developers, but I 
thought I would at least mention it, it's something I personally would 
change.
