Performance issue with GNU/ld and DLL

[Pascal Obry]

Hello,

This is a performance issue report when building DLL on Windows. To
reproduce I have attached a python script (to generate C files).

The steps to reproduce are:

Run gen.py on an empty directory.

$ gcc -c *.c

$ time gcc -o main.exe *.o

takes 0.4 seconds.

$ time gcc -shared -o dll.dll *.o

takes 12 seconds.

It seems that the times goes exponentially. I had generated 1000 files
instead of 200 (N=1000 in gen.py) and I had to kill the linker command
after 10 minutes.

Is that a known problem?

Is there a workaround?

Thanks in advance.

Pascal.
