Some Amiga history here. Back in the beginning, when Autoconfig memory
was just a glimmer in Dale's eye, there was the "Developers Kit." This
included, among other things, a copy of the MetaCompCo assembler and
Lattice C version 3.02 labeled as "Amiga C V1.0". Now in those early
times, it was very difficult to make a program that could run both
from the CLI and the Workbench, so there were two startup modules
supplied. AStartup.o would collect the WorkBench startup message, and
LStartup.o would parse CLI arguments into that ever popular argv array.

Time passed and Commodore stopped supporting Amiga C, more by attrition
than by design I suspect, and Lattice began to market and improve their
product. Now at the 4.0 version number. By now, Lattice had figured out
that you didn't *really* need two startup modules since one could do the
work of both AStartup and LStartup, and since their other compilers all
used c.o they combined the capabilities of both startups into their one
c.o startup module. The only problem with this was that to do this they
were forced to open a window on the workbench when they started up so that
printf's and other stdio operations wouldn't guru the code. They do give
you an out however by letting you recompile _main.c with TINY defined.
I guess they figure that if you know how to do that then you won't leave
a printf() to stdout in your code.

Carolyn Scheppner has done some startups that are available on BIX that
allow for reentrant code.

These opinions are my own and no one elses, but you knew that didn't you.
