MySQL Bugs: #18151: Var rem_size conflicts with #define rem

Bug #18151	Var rem_size conflicts with #define rem_size in /usr/include/sys/xmem.h
Submitted:	11 Mar 2006 9:54	Modified:	20 Jul 2006 8:47
Reporter:	Ralf Becker	Email Updates:
Status:	Duplicate	Impact on me:	None
Category:	MySQL Server: Compiling	Severity:	S3 (Non-critical)
Version:	5.0.21-BK, 5.0.19	OS:	IBM AIX (AIX 5300-03)
Assigned to:	Assigned Account	CPU Architecture:	Any

Description:
In function greedy_search (mysql-5.0.19/sql/sql_select.cc) a temporary variable
 uint rem_size;
is used with conflicts with
 #define rem_size        u2._subspace_id2
from /usr/include/sys/xmem.h
This causes the compiler error:
"sql_select.cc", line 3969.13: 1540-0063 (S) The text "." is unexpected.

I'm using AIX 5300-03 with vac(pp) 8.0.0.0

How to repeat:
Use AIX 5300-03 with vac(pp) 8.0.0.0
 and build database

Suggested fix:
My quick fix:
replace all rem_size in mysql-5.0.19/sql/sql_select.cc by rem_Size

Thank you for a problem report. Sorry, but we have no AIX 5.3 available for testing. On our AIX 5.2 machine I was not able to found the #define you refered to:

So, please, send the same grep results and xmem.h version from your system and exact configure command line that was used. This is the only way for me to verify the problem really exists.

Verified on 5.0.21-BK sources (line 3969 of sql_select.cc still contains 

uint rem_size;

in thjis version), based on the results of two last comments. This should be fixed to make successfull builds on AIX 5.3 possible.

This is a duplicate of bug#17648
