The rationale behind these patches are pretty much in the source comments. MSVC issues with:
*) "Variable Length Arrays"
*) 'restrict` keyword.
*) And '<strings.h>'.
Adds a new interface for constructing, printing and releasing data_t*
structures. The data structure describes typed hierarchical data (much like
json) and then provides a function for dumping it to a file descriptor.
It comes with a small test.
