No, there is no danger. <stdint.h> with intptr_t and uintptr_t is supported
on all platforms for at least 3 years. Microsoft MSVC was the last system
to implement it.

But one can not rely on everything that is supposed to be present in <stdint.h>.
See https://www.gnu.org/software/gnulib/manual/html_node/stdint_002eh.html for
details.
