[Sbcl-devel] sbcl-2.6.4 release - build problems on OpenIndiana/illumos

[Andreas W. <A.W...@gm...>]

Hi all,

In order to build the new 2.6.4 release I had to patch out two 
definitions (c_ispeed and c_ospeed) from sb-posix because our termios.h 
lack them:

Remove two elements that are not available in illumos termios.h

I haven't found their definitions on my linux machine (cachyos) either.
Searching for termios in 
https://pubs.opengroup.org/onlinepubs/9799919799/ shows that our 
termios.h matches the latest official POSIX definition.

Andreas
