dnl ============================================================
dnl We define the macro GLIBC_PROVIDES to do an AC_PROVIDE for
dnl each macro which appears in configure.ac before the sysdep
dnl configure scripts are run. Each sysdep configure.ac does
dnl LIBMPU_PROVIDES first, to avoid any AC_REQUIREs or
dnl AC_BEFOREs duplicating their code.

dnl
dnl    Many 64-bit platforms today use an LP64 model (including Solaris,
dnl    AIX, HP-UX, Linux, macOS, BSD, and IBM z/OS).  Microsoft Windows
dnl    uses an LLP64 model.  The disadvantage of the LP64 model is that
dnl    storing a long into an int may overflow.  On the other hand,
dnl    converting a pointer to a long will “work” in LP64. In the LLP64
dnl    model, the reverse is true.  These are not problems which affect
dnl    fully standard-compliant code, but code is often written with
dnl    implicit assumptions about the widths of data types. C code
dnl    should prefer (u)intptr_t instead of long when casting pointers
dnl    into integer objects.
