I have noticed that Cygwin does not implement llrint. However,

Are there any plans to implement llrint (in the near future)?
Perhaps if you would submit a patch to newlib, something may happen.
Telling me what newlib is would greatly help in this regard :-)
Newlib is the library that Cygwin uses for some standard functions (math
and otherwise).
(The only way to interpret this question is "what is the connection
between newlib and Cygwin", as a quick Google would have pointed you to
the newlib webpage).
Yes, I was not precise. I was unsure about the relationship between
Cygwin and newlib.
I understand that adding llrint to Cygwin is probably not hard at all
for somebody familiar with Cygwin. However, I am not such a person and
I don't even have a Windows environment around to test any modifications
I might make.
We are about to make an MPlayer release and unfortunately it will not
compile on Cygwin due to the missing llrint. I would appreciate to know
if this is going to get addressed so that I can put an appropriate
comment in the release notes.
What's wrong with adding llrint to your code (perhaps with a #define,
i.e.,
#define llrint my_llrint
typeof(llrint) my_llrint(...) { ... }
)?
It is ugly and it is a workaround for a problem that should be solved
outside of FFmpeg. Should every project using llrint add that
workaround? No, Cygwin should be fixed.
