Replace flex malloc functions with Python memory management

[Bastian Kleineidam]

Hello,

I wrote a HTML parser in flex/bison as a Python extension module.
To use the Python memory management, I used
%{
#define malloc PyMem_Malloc
#define realloc PyMem_Realloc
#define free PyMem_Free
%}
%%
... [flex directives]
%%
#undef malloc
#undef realloc
#undef free

Perhaps it would be a feature for flex to add options for this, for example
flex-malloc=PyMem_Malloc.


Greetings, Bastian
