Yep, I see that too:
gcc -O2 -fno-strict-aliasing -Wall -Wmissing-prototypes -Wmissing-declarations
-O1 -Wall -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wcast-align
-Kthread -kthread -pthread -pthreads -D_REENTRANT -D_THREAD_SAFE
-D_POSIX_PTHREAD_SEMANTICS -fpic -I. -I../../../src/include
-I/usr/local/include/readline -I/usr/contrib/include -I../../../src/port -DFRONTEND
-c -o fe-auth.o fe-auth.c
gcc: unrecognized option `-Kthread'
gcc: unrecognized option `-kthread'
gcc: unrecognized option `-pthreads'
What is happening is that config/acx_pthread.m4 is now adding any option
that allows it to compile, so we get -pthread and -lpthread for Linux,
among other things.
The problem is that for certain flags, gcc reports the option as
unrecognized, but doesn't generate an error. I can't think of how to
check for such output from the compiler from configure.
