Re: [vox-tech] Chicago?
Jay, I would also recomend cygwin plus xfree86 ( for x, if you must use windows). This will give you a UNIX environment on Windows and also a free replacement for eXceed. Cygwin xfree86 has worked really well for me at work on NT and 2000. It is possible to get it to work decently on XP and I have had speed problems with win95/98. As far as MS products being offered on UNIX, they actually have IE 5 for Solaris (ok flame away), I have used it on my ultra 5. I really prefer Opera or mozilla though. As far as building your own system, I would recomend building one just becuase it is plain fun to do (even if it is a cheap system). I am going to the computer show in Vallejo on Saturday if anyone is interested. I am going to pick up parts to build a lower end system for my 4 year old son (who is very close to learning how to build one himself).

I've never really used it, but Konqueror's SMB support looks pretty slick. Just type "smb://machinename" in the URL bar and you can move through the other machine just like a local folder.

What I would do is perform a test at the beginning of function as to
whether variable should be assigned an initial value or not.
void function ( ..., long double dr)
{
static bool inited = false; /* Need for this - it's
C99-specific, so don't #include it
if you intend for it to be
portable to C90: instead, define
bool and false yourself. */
static long double variable;
if (!inited)
{
variable = expensive_calculation * dr;
}
...

What version gdb are you using? I have 5.1. I can't really test your

ANSI C added the ability to initialize auto variables in functions to the
K&R language. Constant initialization of auto variables was considered a
big step forward in usability at the time. :)
Initializers for static variables inside functions may be non-constant
expressions in C++, because the compiler automatically generates the
"if" code.
Static variables at module scope (outside functions, with no
external linkage) are automatically pre-initialized to zero in C. This
fact can be used to setup a flag for the function to test to see whether
that function has been called yet.
(In C++, initialization of variables at global scope is complicated by the
allowance for user-defined constructors. These are called by startup code
prior to calling main, in the sequence they were declared in within
modules, and those sets of constructors for each module are called in
implementation- defined sequence (you can't determine whether the module
constructors from module A will be called before those in module B within
the language).)

Hmmm... ummm... hmmm... Think, think...
Yes. If they aren't calculated at compile time, then you need some way to
tell whether a function call during runtime is the "first call". This
would have to be something like:
int function(int arg)
{
if(first_call())
{
/* initialize static variables */
}
blah blah...
}
This adds hidden overhead to a function call, which would be a no-no for C.

does this apply to static variables too? i have a situation where a
function is called many times over:
void function( ..., long double dr)
{
long double variable = expensive_calculation * dr;
...
}
i'd like to declare variable as static, since both expensive_calculation
and dr remain constant through the entire program. i can't declare dr
as being global because it depends on other parameters that need to be
calculated at run time (but otherwise don't change).
when variable is declared static, it generates the same error message --
a variable initializer. so i assume local static variables are also
first computed at compile time?
