Issues with 2.6.4 release candidates

This page is supposed to contain all issues discovered while testing release candidates and their status. Make sure to include information about the platform where the problem appears (if applicable). Once the issue gets resolved, you should strike it over and add number of SVN revision fixing it. If the revision number refers to a SVN repository different from "fpc" (i.e. "fpcbuild" or "fpcdocs"), include information about the SVN repository too.

Example:

1. cpu-os: IE209101221 while compiling XYZ.pas - r123456
2. docs: missing description of XYZ
3. readme.txt: wrong version number - r654321 (fpcbuild)

Issues with 2.6.4-rc1

• *make clean* and *make distclean* don't clean anything in the package directories handled by fpmake (fastcgi and fcl-web) when FPC is a cross-compiler fixed r26844
• document the issues on User Changes 2.6.4 that triggered the changes performed in Lazarus
  • [r40410](http://svn.freepascal.org/cgi-bin/viewvc.cgi?view=revision&root=lazarus&revision=40410) (already documented on [User Changes Trunk](/wiki/User_Changes_Trunk)),
  • r43275 Denied: fppkg/fpmake is beta in 2.6.x, not documented functionality.
  • r43371 Denied: Exact reason for this construct unknown. insertitem overload exists since rev 1?
• cross-building broken r26134
• packages/fcl-db/tests/dbtestframework.pas has compile errors:

 '''it is because there is used array constructor, which was introduced in FPC>=2.7.1
 solution is remove whole test TTestFieldTypes.TestOpenSpecialStatements from testfieldtypes.pas'''
