Summary: VC6 cannot always convert uint64 to float
Product: Apache httpd-2
Version: 2.3-HEAD
Platform: PC
OS/Version: Windows 2000
Status: NEW
Severity: normal
Priority: P2
Component: Core

ReportedBy: [EMAIL PROTECTED]
Change 617890 (change 649114 for 2.2.x) causes problems for some Windows VC6
compilers.
The default VC6 compiler cannot convert unsigned 64-bit int's to float:
"error C2520: conversion from unsigned __int64 to double not implemented, use
signed __int64"
If the optional Microsoft "Processor Pack" is installed, this conversion works
OK.
Unfortunately, the Processor Pack is only available up to VC6-SP5, so those
users who have installed VC6-SP6 are out of luck.
Since a signed 64-bit int would allow up to 10^20 bytes, changing the
totalread, totalbread, and totalposted variables to apr_int64_t instead of
apr_uint64_t would allow all VC6 users to continue to compile support/ab.c.
There are no problems with later Microsoft compilers (VC7, VC8, VC9). This is
really a Microsoft VC6 compiler weakness, not an Apache bug - but since VC6 is
the default compiler for apache.org builds this change would be helpful.
