Subject: [wishlist] configure option to disable tmpnam
Date: Wed, 25 Oct 2017 17:26:37 -0700

[Message part 1 (text/plain, inline)]

It would be nice to have a configure option to disable/enable including the POSIX function tmpnam.
It may give Guile a more "code secure" option to have the default be disabled.

I tried to generate a patch, but I could not get it to work both ways (disable and enable).  My autoconf
knowledge and skills are lacking. 

Here is what I tried (THIS DOES NOT WORK)
