Package: autoconf-archive
Version: 20180313-1
Severity: normal
Tags: patch upstream
Forwarded: https://savannah.gnu.org/patch/index.php?9750
The PTHREAD_PRIO_INHERIT check can trigger a -Wunused-variable warning,
which can be turned into an error when -Werror is used, with the
consequence that PTHREAD_PRIO_INHERIT appears to be missing:
configure:14787: checking for PTHREAD_PRIO_INHERIT
configure:14803: gcc -o conftest -O2 -Wall -Wold-style-declaration
-Wold-style-definition -Wmissing-parameter-type -Wmissing-prototypes
-Wmissing-declarations -Wmissing-field-initializers -Wc++-compat
-Wno-error=unused-function -Werror -Wcast-function-type -Wcast-align=strict
-pthread conftest.c >&5
conftest.c: In function 'main':
conftest.c:28:5: error: unused variable 'i' [-Werror=unused-variable]
int i = PTHREAD_PRIO_INHERIT;

This issue can easily be avoided by adding a "return i;". See attached
patch.
