[Bug-gnulib] mkstemp

mkstemp.m4 currently checks via AC_TRY_RUN that mkstemp can create 30
consecutive files.  Would it be reasonable to want to check that one has
mode 0600?  This is the current comment and handling in CVS:

~   . . .
~        if (fp == NULL) free (fn);
~    #if (__GLIBC__ - 0 < 2 || __GLIBC__ - 0 == 2 && __GLIBC_MINOR__ - 0
== 0)
~        /* mkstemp is defined to open mode 0600 using glibc 2.0.7+ */
~        else chmod (fn, 0600);
~    #endif /* GLIBC API version <= 2.0 */
~    . . .

Has anyone heard of similar broken mkstemp implementations or is it only
GLIBC?  I haven't found anything recent in the archives.

Derek
