# On some hosts (e.g., HP-UX 10.20, SunOS 4.1.4, Solaris 2.5.1), mkstemp has a

# Other systems lack mkstemp altogether.

# On OSF1/Tru64 V4.0F, the system-provided mkstemp function can create

|
|
# only 32 files per process.
|

# On systems like the above, arrange to use the replacement function.
