Behaviour of tmpnam

[Alexander Klimov]

Hi.

I tried to run `make check' on CVS version and it is failed with
misterious message 
with GUILE_LOAD_PATH: /export/home/ask/build/guile-core
ERROR: In procedure mkdir:
ERROR: No space left on device

uname -a:
SunOS iridium 5.6 Generic_105181-20 sun4u sparc SUNW,Ultra-5_10

I know that my /var/tmp is full, and because of this I use
TMPDIR=/tmp and every good program regards this (gcc at least), and it is
exported:
guile> (system "echo $TMPDIR")
/tmp
0

Lets return to our tests. It is looks like one of tests use (tmpnam) and
behaviour of this function is strange:
guile> (tmpnam) 
"/var/tmp/aaa4dZFP_"

It is strange, because documentation said: `This function is implemented
with the `tmpnam' function in the system libraries', and documentation of
tmpnam said (tmpnam(3S)): 
     tempnam() allows the user to control the choice of a  direc-
     tory.   The argument dir points to the name of the directory
     in which the file is to be  created.   If  dir  is  NULL  or
     points  to  a  string  that is not a name for an appropriate
     directory,  the  path-prefix  defined  as  P_tmpdir  in  the
     <stdio.h> header is used.  If that directory is not accessi-
     ble, /tmp will be  used  as  a  last  resort.   This  entire
     sequence  can be up-staged by providing an environment vari-
     able TMPDIR in the user's environment, whose  value  is  the
     name of the desired temporary-file directory.
