284649 - Compiling mozilla-1.7.5 with GCC 4.0 fails on x86_64

Status: RESOLVED DUPLICATE of bug 269823

(Core :: Networking, defect)

Description

[Jonathan Briggs]

User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.7.5) Gecko/20050207 Epiphany/1.4.8
Build Identifier: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.7.5) Gecko/20050207 Epiphany/1.4.8

The build fails with this error message:
nsHttpConnectionMgr.cpp:837: error: cast from 'void*' to 'PRUint32' loses precision

This is because void* is 64-bits and PRUint32 is 32-bits and the compiler is
worried for you.  I believe it needs to be cast into a 64-bit integer first.  I
usually fix this by casting to intptr_t but that definition is not visible in
the source file.

Reproducible: Always

Steps to Reproduce:
1. Try to build Mozilla on 64-bit Linux on Athlon 64.

Actual Results:  
It fails.

Expected Results:  
It should build with GCC 4.

I'm sure I've seen a bug report about this before... I can't find it currently

But Bug 284809 would have fixed this issue, too ;).
