Comment:

 Hi,

 I found a cause and solution to this on Debian/Wheezy. Using
   CFLAGS="... -Werror-implicit-function-declaration"
 on the ./configure like triggers an error in the test compile for X:

 (config.log)
 {{{
 ...
 configure:4791: checking for W11
 configure:4819: checking for X
 configure:4884: gcc -E  conftest.c >/dev/null 2>conftest.out
 configure:4960: gcc -o conftest -ggdb -march=amdfam10 -Wall -Werror-
 implicit-function-declaration -fno-common -Wextra -Wunused    -Wl
 ,--export-dynamic conftest.c -lXt  1>&5
 configure: In function 'main':
 configure:4956:1: error: implicit declaration of function 'XtMalloc'
 [-Werror=implicit-function-declaration]
 cc1: some warnings being treated as errors
 configure: failed program was:
 #line 4953 "configure"
 #include "confdefs.h"

 int main() {
 XtMalloc()
 ; return 0; }
 configure:5627: checking whether to use Curses
 configure:5646: checking for curses.h
 ...
 }}}


 who's forgetting to do the #include? a bug in autoconf or one of ours?

 ./configure'ing without -Werror-implicit-function-declaration leads to X
 being detected and built.
