I wrote a review of 5 C compilers for the Dutch magazin start (no connection
with the US magazin) a few months ago. In it we compared (Daan Jitta and me)
Laser C, Lattice, MarkWilliams, Aztec and Turbo C.
Nearly all categories were won by Turbo. The category that it does worst
in is the reliability of its libraries. This is explained by the fact that
it is still a rather new product.
Here are the results of some benchmarks:
Savage:
compil exec error
Aztec 10.3 68.04 -3.177E-07
Laser 9.5 36.27 +1.737E-10
Lattice 32.7 40.01 -3.177E-07
MWC 27.1 85.14 -1.188E-07
Turbo 12.6 31.82 +1.737E-10
Dhrystone:
comp Dhrystones/sec
Aztec 17.2 1137
Laser 12.1 845
Lattice 38.6 786
MWC 29.5 1048
Turbo 17.6 1702 (compilation delayed by two pages warnings (ANSI))
Next I compiled a larger program, consisting of about 20 files (> 300K together)
comp exec size,size during execution
Aztec 573 97 74924,83230
Laser 263 99 91006,96444
Lattice 1230 111 103668,100554
MWC 633 84 78079,83222
Turbo 201 74 62180,68688
This last program didn't use floating point and used hardly anything of
the libraries.
With other programs MWC usually beats Aztec in the length of the file.
The running time difference between MWC and Aztec in the last example
is mainly due to the fact that Aztec cannot use predecrement and post
increment.
The above compilations were from ramdisk (Mega 4). The compiler was sitting
on hard disk and had to be called each time by make.
registers were used as much as possible.
This last program was designed with MWC and fairly much optimized to produce
efficient code with it.
In my programs typical rates are that code is about 20% shorter and faster.
By the way:
Turbo C was made by Heimsoeth with much help from Borland.
When it is a hit in Germany they will sell it in the US under the name Borland.
I haven't seen the official release of the assembler and the debugger yet.
The assembler (in beta version) uses motorola instructions and looks in its
use like what the DRI assembler should have been. Because it hasn't been
released yet I don't know about the macro facilities. My manual is a file
that contains about 50 lines or less about the assembler. Its a good
workhorse though.
The debugger is at assembler level (the source level debugger will come
later. If it looks like the one on the PC it will be very good) and looks
a little bit like a very much improved SID.
Price of turbo is less than DM200 in Germany which is a little over $100.

Hello,
mail to chad@decwrl.dec.com bounces, so, since this might be of
american interest, I send it to the list. It is an information
about price and availability of Turbo-C for Atari ST in Germany.
------------- original mail to chad starts here -------------
Hi,
in Germany, Borland products are sold from many firms, but the
original distributer is Heimsoeth in Munich.
Heimsoeth Software GmbH & Co. KG
Lindwurmstrasse 88
8000 Muenchen 2
++49-89-72010-201 or
-202
The price is DM 228,- (about $115,-) for the Compiler and DM 342,- (about
$170,-) for Compiler, Assembler and Debugger, but I am not sure, whether
the debugger is already available.
If you are interessted, I can send you address and phone number of the
firm in Munich, which ported the whole thing.
CU Carsten.

Just to clarify the situation: the menus of TURBO-C ARE english! Only documentation and online-help are in German. Perhaps some publishing company should offer an english documentation for Turbo-C? Julian Reschke
