           Summary: missing C standard headers
           Product: Fedora Core
           Version: devel
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: normal
         Component: perl
        AssignedTo: jvdias(a)redhat.com
        ReportedBy: jvdias(a)redhat.com
         QAContact: dkl(a)redhat.com
                CC: fedora-perl-devel-list(a)redhat.com

Description of problem:

All perl versions on Linux / glibc / gcc systems fail to look for the 
C standard header files in the correct location, eg. :

  stddef.h  syslimits.h  stdarg.h  float.h  stdbool.h  

These are gcc built-in headers, and cpp searches for them in the gcc 
architecture specific include directory before the system include directory:
  /usr/lib/gcc/${arch}-${os}/${gcc-version}/include

During the perl build, perl does not look for any headers in the 
gcc architecture specific include directory, but instead either 
fails to find the header at all, or finds versions of them used 
only by the kernel, eg. as shown by this excerpt from a log of a 
Rawhide perl build :
---
+ for i in asm/termios.h syscall.h syslimits.h syslog.h sys/ioctl.h sys/socket.h
sys/time.h wait.h ...
...
+ /var/tmp/perl-5.8.7-0.5.fc5-root-jvdias//usr/bin/perl
/var/tmp/perl-5.8.7-0.5.fc5-root-jvdias//usr/bin/h2ph -a -d
/var/tmp/perl-5.8.7-0.5.fc5-root-jvdias/usr/lib/perl5/5.8.7/i386-linux-thread-multi
syslimits.h
Can't open syslimits.h: No such file or directory
syslimits.h -> syslimits.ph
---

( empty syslimits.ph - no syslimits.ph shipped )

---
+ /var/tmp/perl-5.8.7-0.5.fc5-root-jvdias//usr/bin/perl
/var/tmp/perl-5.8.7-0.5.fc5-root-jvdias//usr/bin/h2ph -a -d
/var/tmp/perl-5.8.7-0.5.fc5-root-jvdias/usr/lib/perl5/5.8.7/i386-linux-thread-multi
asm/termios.h
...
linux/stddef.h -> linux/stddef.ph
---

No <stddef.h> shipped, only <linux/stddef.h>, which is meant to be used only
by the kernel.

This results in many system headers that reference the C standard headers 
being unusable because the C standard headers are not found 
(eg. sys/resource.ph -> bits/resource.ph -> linux/types.ph -> stddef.ph 
 -> stddef.ph not found,
 bug 170088 ).

The perl build process should find the C standard headers in their correct 
location, as many system perl headers that are shipped by perl reference them.

Version-Release number of selected component (if applicable):
ALL

How reproducible:
100%

Steps to Reproduce:
$ perl -e 'require "sys/resource.ph";'

Actual results:
Fails due to missing stddef.ph

Expected results:
No error
