Hi,
When using embedded Racket, I noticed it can write to stderr directly:
static void got_sigchld() XFORM_SKIP_PROC
{
if(-1 == write(2, "SIGCHLD handler called (some thread has SIGCHLD
unblocked)\n", 59)) {
}
}
Is it be possible to disable this for embedded configuration as it
messes up st
In addition to what Sam mentioned, if you use state in your function,
then the optimizer tends to give up early, so you can often stick a
set! that isn't doing anything to make it give up.

I'm fuzzy on the details, but I believe recent versions of Windows
handle applications that to dump potentially conflicting things in
System32, by using a "side-by-side" configuration strategy? If so,
perhaps some of the items are in fact some variety of link rather than
a normal file. As Jay ment
It actually _is_ in my PATH already:

(Other members of PATH omitted.) Weird, huh? Something is wonky. I even
tried changing the capitalization of "system" on the off chance that case
mattered, but nope.

pre-base.rkt makes my head hurt, too. It's in racket\src\racket\src\file.c.

Oh! I just remembered that we recently patch Racket with Racket blinders so
that it doesn't acknowledge the existence of any language not implemented a
Racket macro. I think you're just out of luck unless you want to downgrade.

If you're searching through PATHt, you should be able to use
find-executable-path.

I don't think that the file (in this case, java.exe) is a symlink, and it's
definitely not a shortcut. What really worries me is that it doesn't come
up when calling (directory-list), which doesn't have as strong a filter as
file-exists?. Is directory-list supposed to ignore anything?
I could pipe
file-exists? checks if it a FILE, it returns false on directories, links
(shortcuts), special files, etc.
Could that be it?

Dear Benevolent Racketeers,
I just installed DrRacket 5.3.1 on my Windows 8 Laptop. (Yes,
Windows 8, please don't laugh at me. :-) ) I have not checked
this on other operating systems or other versions of Racket.
One of my Racket projects scans the PATH directories to locate
the Java executable,

See the `--disable-inline` flag to `raco make`.
