small (very ) compilation speedup

[andreas moroder]

Hello,

not all of us have a fast machine ( I have a slow PII 350 ) so even a small 
speedup of compilation is welcome. Here my proposal.

There are files in samba that are compiled two times, one time as standard 
obj, the second one as PIC code.

What about to change the makefile to do the following steps:

1. Compile with -E -oname.i to create a precompiled file

2. compile this precompiled file as .o and .po

The speedup while testing with reply.c is 5 %, but maybe it's worth the effort

Bye

Andreas
