Fixes #8195. This PR doesn't fix all the warnings from #8195, but fixes many of them (e.g., I didn't get the "string might be truncated" warnings on my Mac). This is an adaptation of 14aa5fae3c42f14a1c6a259dede93d5ca7ecb82c from master; it drops some things that aren't relevant here on the v4.1.x branch and adds a few more warnings fixes that are relevant here on v4.1.x that aren't relevant on master.

/** @file:
|
|
* Creates an operating system-acceptable path name.
|
|
*
|
|
* The opal_os_path() function takes a variable number of string arguments and
|
|
* concatenates them into a path name using the path separator character appropriate
|
|
* to the local operating system. NOTE: the string returned by this function has been
|
|
* malloc'd - thus, the user is responsible for free'ing the memory used by
|
|
* the string.
|
|
*
|
|
* CRITICAL NOTE: The input variable list MUST be terminated by a NULL value. Failure
|
|
* to do this will cause the program to suffer a catastrophic failure - usually a
|
|
* segmentation violation or bus error.
|
|
*
|
|
* The function calls orte_sys_info() to ensure that the path separator character
|
|
* has been identified. If that value cannot be identified for some reason,
|
|
* the function will return a NULL value. Likewise, specifying a path name that
|
|
* exceeds the maximum allowable path name length on the local system will result
|
|
* in the return of a NULL value.
