Subject: Rename build-time option TMPDIR to EXIM_TMPDIR
X-Git-Tag: exim-4_87_RC4~22
X-Git-Url: https://git.exim.org/exim.git/commitdiff_plain/75286da3fea0f1640b8b4271ffd0098a6ac0a2f8?hp=75286da3fea0f1640b8b4271ffd0098a6ac0a2f8

Rename build-time option TMPDIR to EXIM_TMPDIR

Build-time option TMPDIR included in Makefile clashes with environment
variable of the same name. This breaks tools that make use of that
variable, such as distcc.

The following example demonstrates what's going on:

$ cat Makefile
TMPDIR="/tmp"
all:
	env
$ export TMPDIR=test
$ make | grep ^TMPDIR
TMPDIR="/tmp"

distcc error (note the extra quotes):
ERROR: can't use TMPDIR ""/tmp"": No such file or directory
