On AIX in a testdir of all modules, using
'./configure --disable-year2038 && make' I see the following failure:

Trimmed the rest of the errors for strtoll, strtoul, etc.
This is the same as Bruno found on Solaris 11 OmniOS previously [1]. The
same fix works in this case.
Pushed the attached patch to fix it.

/* When strtol, strtoll, strtoul, or strtoull is going to be defined as a macro
below, this may cause compilation errors later in the libstdc++ header files
(that are part of GCC), such as:
error: 'rpl_strtol' is not a member of 'std'
To avoid this, include the relevant header files here, before these symbols
- get defined as macros. But do so only on Solaris 11 (where it is needed),
- not on mingw (where it would cause other compilation errors). */
