Hi Everyone,
I'm building Bash 5.1 from sources. This may be of interest:
/usr/bin/ld: ./lib/sh/libsh.a(tmpfile.o): in function
`sh_mktmpname':
/home/jwalton/Build-Scripts/bash-5.1/lib/sh/tmpfile.c:160: warning:
the use of `mktemp' is dangerous, better use `mkstemp' or `mkdtemp'
It's a spurious warning.
mktemp() would only end up being used (with all its issues) if the OS
doesn't provide a DEV FD or there's no mkdtemp(). In other (safe)
Operating Systems, it would be possible to avoid the warning by
building a slightly different libsh.a in such case.
