Yes, our Cygwin support has rotted in a variety of small but exotic
ways.
I'm in the process of fixing the problems. The enclosed patch applies
to the development branch or the v6.1.1 release candidate, and it might
work for you, but I'm still checking it.
The fixed-up implementation will be limited in various ways, such as
not supporting places or futures, but I should be able to make all the
basics work.

Hi,
I downloaded racket-6.1-src-builtpkgs.tgz. According to src/README, this
should be compilable on cygwin with --enable-shared. I did not have
success doing so.
The first problem was dynsrc/mzdyn.c failed to
compile due to expected specifier-qualifier-list before ‘(’ token
error at schemex.h:1004. The line here reads
(*scheme_jit_find_code_end)(void *p);
I grepped some and stuck a void* in front of it, and compilation went ahead.
But then it failed with 'WINDOWS_DEFAULT_STACK_SIZE' undeclared (first use
in this function) at eval.c:546
intptr_t sz = WINDOWS_DEFAULT_STACK_SIZE;
To update, I went ahead and copied the macro from where it was defined for
windows over to the cygwin section. The next errors were due to three
consecutive assignments in schemex.inc that were accessing undefined
functions
(ones related to freeze or frozen - unfortunately I don't have the code
right now), so I commented those lines out. Now I have a successful link,
except it segfaults during make install. This is because this target runs the
racketcgc (spelling?) executable, which immediately seg faults (I tried
running
it in the shell to be sure).
I hope someone has more clues about this. Thank you.
I
am at a loss at this point. Is racket not expected to compile on
cygwin? If so, can someone remove the cygwin parts in src/README?
Thank you.
