    28in compiling, installing and running GNU Emacs.  Try doing Ctl-C Ctl-t

     216** Emacs compiled with Gtk+ crashes on startup on cygwin. 
     217 
     218A typical error message is 
     219  ***MEMORY-ERROR***: emacs[5172]: GSlice: failed to allocate 504 bytes  
     220  (alignment: 512): Function not implemented 
     221 
     222Emacs supplies its own malloc, but glib (part of Gtk+) calls memalign and on 
     223cygwin that becomes the cygwin supplied memalign.  As malloc is not the 
     224cygwin malloc, the cygwin memalign always returns ENOSYS.  A fix for this 
     225problem would be welcome.

    309326IF YOU DON'T USE THE FORM OF INTERLOCKING THAT IS NORMAL ON YOUR 
    310327SYSTEM, YOU CAN LOSE MAIL! 
    311  
    312 If your system uses the lock file protocol, and fascist restrictions 
    313 prevent ordinary users from writing the lock files in /usr/spool/mail, 
    314 you may need to make `movemail' setgid to a suitable group such as 
    315 `mail'.  You can use these commands (as root): 
    316  
    317         chgrp mail movemail 
    318         chmod 2755 movemail

    23572366addition, the Cygwin GCC 3.4.4-2 has problems with generating debug 
    23582367info.  Cygwin users are advised not to use these versions of GCC for 
    2359 compiling Emacs.  GCC versions 4.0.3 and 4.1.1 reportedly build a 
    2360 working Cygwin binary of Emacs, so we recommend these GCC versions.

     2369build a working Cygwin binary of Emacs, so we recommend these GCC 
     2370versions.  Note that these three versions of GCC, 4.0.3, 4.1.1, and 
     23714.1.2, are currently the _only_ versions known to succeed in building 
     2372Emacs (as of v22.1).

    23622374*** Building the native MS-Windows port with Cygwin GCC can fail.

    24032415patch to assert.h should solve this:

     2437*** Building the MS-Windows port with Visual Studio 2005 fails. 
     2438 
     2439Microsoft no longer ships the single threaded version of the C library 
     2440with their compiler, and the multithreaded static library is missing 
     2441some functions that Microsoft have deemed non-threadsafe.  The 
     2442dynamically linked C library has all the functions, but there is a 
     2443conflict between the versions of malloc in the DLL and in Emacs, which 
     2444is not resolvable due to the way Windows does dynamic linking. 
     2445 
     2446We recommend the use of the MingW port of GCC for compiling Emacs, as 
     2447not only does it not suffer these problems, but it is also Free 
     2448software like Emacs.
