#34247 [NEW]: configure claims g++ does not support shared libraries (when used as LD)

From: arattink at correct dot net
Operating system: Linux 2.4.25 SMP
PHP version:  5.1.0RC1
PHP Bug Type: *Configuration Issues
Bug description:  configure claims g++ does not support shared libraries (when 
used as LD)

Description:

The configure fails to discover that that g++ (ie LD=/usr/bin/g++)   
supports shared libraries.   
>From the output:   
   
checking whether the gcc linker (/usr/bin/g++) supports shared   
libraries... no   
   
I can assure you that g++ (used as 'ld) does support shared libs. I   
need to use g++ specificly because ld does not link C++ libraries   
correctly and we use some C++ code in our own extensions.  
   
g++ --version ==>   2.95.3   
   
For the record: *only* LD is set, not CC or CXX or any xxxFLAGS. 

Reproduce code:
---
LD=/usr/bin/g++ ./configure --disable_all

Expected result:

checking whether the gcc linker (/usr/bin/g++) supports shared 
libraries... yes 
 
 

Actual result:
--
checking whether the gcc linker (/usr/bin/g++) supports shared   
libraries... no   
   
Unfortunately it is nigh impossible to figure out what configure   
does.
   
I also tried gcc-3.4.3 which claimed g++ did and did not support it   
in the same run, but in the end refused to build the .so file anyway.   
I also tried 'LD="g++ -v"' and '--with-gnu-ld' but to no avail.   
All these tests on a freshly untarred tarball to be sure.   
   
 Yours sincerely,   
Arnoud Rattink.

#28975 [Com]: printf("%6.2f") and values less than 1 gives wrong output

 Status:   Open
 Bug Type: Output Control
 Operating System: Linux
 PHP Version:  Irrelevant
 New Comment:

Line 401/403 in ext/standard/formatted_printf.c should be 
removed.  
 
/*  if (precision > 0) { 
width += (precision + 1);
}*/ 
 
I'm not a PHP-developer, but 'width' passed to 
php_sprintf_appenddouble should be passed on to 
php_sprintf_appendstring unaltered. It seems that in most cases 
precision is garbled to 0 so it works most of the time.

Description:

A printf of float values less than 1 gives an incorrect output. It
looks like the numbers before the dot equal the width specifier...

This happens with every tested PHP version (4.3.7, 5.0.0RC3 and CVS)

With PHP 4.3.6 both outputs were wrong...

Reproduce code:
---
$a = sprintf ( "%06.2f" , 0.5 );
$b = sprintf ( "%06.2f" , 1.5 );
var_dump($a);
var_dump($b);


Expected result:

string(6) "000.50"
string(6) "001.50"


Actual result:
--
string(9) "00.50"
string(6) "001.50"
