configure scripts look for and read a local configuration file given by the
environment variable CONFIG_SITE. This can set variables such as prefix.
Racket’s build system was assuming that prefix would be set to NONE unless a
--prefix command line argument was given. But it could be set by a
CONFIG_SITE configuration file instead.
Hence, for in-place build add an explicit --disable-useprefix option, to
cause any prefix setting to be ignored, and use that in the top-level
Makefile.
Regenerate the configure scripts to get the updated code.
Revert the part of 39a96dd699 that hides the provenance of these
accessors. Although exposing the fact that the predicates are for
structure properties constrains some internal representations, that
constraint seems unlikely to matter, and exposing the procedures as
property predicates is more consistent with the documentation and the
implementation (especially for Racket CS).
Closes#2904
Improve gcc detection in configure script
We have been detecting gcc by the CC variable but this fails under
ubuntu for example where you might specify CC='gcc-8' to ./configure.
Also consider clang impersonator to be gcc.
Related to #2890
Support continuation-mark inspection proportional to the amount that
needs to be inspected, instead of having to build a list of length
propotional to the size of a continuation.
In Racket CS, use iteration to improve exception-handling chaining.
Traditional Racket already used similar functonality internally.
Add a special case for a real divided by a complex, and remove
(probably) misguided special cases for inexact zero real and imaginary
parts. These changes bring complex `/` further in line for Racket and
Racket CS.

relevant phase.
* Added a 'CONTRIBUTING.md' file
* Update CONTRIBUTING.md
Added link to blog post based on euhmeuh's suggestion
Co-Authored-By: dstorrs <david.storrs@gmail.com>
* propose shorter guide
* add link "About Pull Requests"
Add a link to a GitHub guide on pull requests (thanks to @spdegabrielle)
Remove some text & links to make the un-rendered file easier to read. The missing links are easy to find from the remaining ones.
Include the defined name (in addition to the provided name) in the
result of `module->exports` and `module-compiled-exports` --- but for
backward compatibility, only if the new optional `verbosity` argument
is 'defined-names.
* Fix gen:dict methods for alists with duplicate keys
This fixes https://github.com/racket/racket/issues/2803.
Note that while this works, the implementation is not particlarly fast.
Especially for iterators.
* Fix tabs
* Make code more efficient
* Fix function definition order
* Import set library
* Preserve order
* Use immutable hash sets
* Remove unused import and remove duplicate checks
* Fix syntax error
