* Added support for X11 modules. * Makefile: change location of FORMS library. * posixmodule.c: turn #if 0 into #ifdef MSDOS (stuff in unistd.h or not) * Almost all .h files: added CPP magic to avoid duplicate inclusions and to support inclusion from C++.

******************************************************************/
The great renaming, phase two: all header files have been updated to use the new names exclusively, and the linker will see the new names. Files that import "Python.h" also only see the new names. Files that import "allobjects.h" will continue to be able to use the old names, due to the inclusion (in allobjects.h) of "rename2.h".

extern void PyOS_InitInterrupts Py_PROTO((void));
This fix (across 4 files in 3 directories) solves a subtle problem with signal handlers in a fork()ed child process when Python is compiled with thread support. The bug was reported by Scott <scott@chronis.icgroup.com>. What happens is that after a fork(), the variables used by the signal module to determine whether this is the main thread or not are bogus, and it decides that no thread is the main thread, so no signals will be delivered. The solution is the addition of PyOS_AfterFork(), which fixes the signal module's variables. A dummy version of the function is present in the intrcheck.c source file which is linked when the signal module is not used.
