c7aa644390 34287: preprocessor for signal name generation. 
Some gcc header files are difficult for the signames2.awk
script to process, so if the preprocessor is gcc give the
option -P to strip out the unwanted additions.

cfd91eac07 Rearrange context saving. 
Variables are now associated with the module that declares them, being
initialised and saved/restored there.  However, as many variables are
used for communication between modules, many of them are set in multiple
places, so the assignment is ambiguous.

18b60d8512 34117: zle: size_t is unsigned, use int instead 
The function wctomb returns an int according to my manpage, and we
furthermore check if it is negative, and then return it, and the function
signature is int, so declaring it as an int seems to make more sense.
