Bootstrap broken on Cygwin

Bootstrap broken on Cygwin

[Angelo Graziosi]

After recent changes [*] to 'strftime', the bootstrap of trunk is broken 
on Cygwin. For example, with rev. 102432:

Could these changes (today)

2008-06-13  Daniel Engeler
	These changes add serial port access.
	[...]
	* sysdep.c [HAVE_TERMIOS] (serial_open, serial_configure):
	New functions.
	[...]

be the cause?

Until 24 hours ago it bootstrapped fine.


Hard times for Emacs on Cygwin these days...


Cheers,
    Angelo.

Re: Bootstrap broken on Cygwin

[Evil Boris]

I am getting a possibly related error on Solaris 2.7 with GCC 3.1:

====
sysdep.o: In function `serial_configure':
/local/2/software/emacs-cvs/emacs/src/sysdep.c:5438: undefined reference to `cfmakeraw'
/local/2/software/emacs-cvs/emacs/src/sysdep.c:5451: undefined reference to `cfsetspeed'
collect2: ld returned 1 exit status
====

After some poking around I found that instead of cfsetspeed there is a
definition of cfsetispeed and cfsetospeed in sys/termios.h.  I cannot
find any mention of csmakeraw.  Here's one place that describes 
possible replacement code:

For what I can see, they are the same errors I found on Cygwin.
