PHP Bug Type: Compile Failure
Bug description: Compiling informix extension fails if compiling out of tree
Description:
------------
1) A harmless error in the Makefile, which only occurs on out of tree
builds is not ignored and causes make to abort.
2) The resulting module is empty, because HAVE_IFX is not defined, because
config.h is not included.
Both of these problems can be fixed by applying the following patch:

Reproduce code:
---------------
curry:/tmp% cp -a php-4.3.7RC1/ext/informix /tmp
curry:/tmp% cd informix
curry:/tmp/informix% phpize
Configuring for:
PHP Api Version: 20020918
Zend Module Api No: 20020429
Zend Extension Api No: 20021010
curry:/tmp/informix% ./configure
[...]
curry:/tmp/informix% make
/bin/sh /tmp/informix/libtool --mode=link gcc
/usr/local/informix/lib/esql/checkapi.o -o libphpifx.a
mkdir .libs
ar cru libphpifx.a
ranlib libphpifx.a
(if test -d /usr/local/informix; then \
THREADLIB=POSIX /usr/local/informix/bin/esql -e -EDHAVE_IFX_IUS
/tmp/informix/ifx.ec; mv ifx.c /tmp/informix/ifx.c; \
else \
touch /tmp/informix/ifx.c; \
fi)
mv: `ifx.c' and `/tmp/informix/ifx.c' are the same file
make: *** [/tmp/informix/ifx.c] Error 1
This is the first problem. It can be fixed by replacing:
mv ifx.c $@
with
mv ifx.c $@ || true
to make make ignore the error, or by explicitely telling make to ignore
all errors in this recipe.
When this problem has been fixed make generates a shared PHP-extension
named informix.so. This extension is unusable, becuase it is empty. The
reason for this is, that ifx.ec does not include config.h and thus
HAVE_IFX in not defined and the contents of the module is ommitted.
