On Fedora 15, compiling with these versions of Lazarus and Freepascal, I get the error below:

And sure enough, going up to the definition of FieldNameQuoteChars on line 74 of mysqlconn.pas, there is a definition that makes FieldNameQuoteChars only defined when compiling with version 2.4.0:
{$IFDEF VER2_4_0}
FieldNameQuoteChars : TQuoteChars;
{$ENDIF}
Should there be a similar thing so FieldNameQuoteChars is also defined on 2.4.2 (and 2.4.1?) or are the newer versions supposed to define FieldNameQuoteChars somewhere else and am I running into another bug?
And sure enough, an ugly (and wrong) patch to change the VER2_4_0 to VER_2_4_2 results in cqrlog compiling...
I'm not sure what the pascal syntax for the correct fix is, so I won't even bother attaching that horrible patch :)
Where can I email the cqrlog spec file, for inclusion in the cqrlog project?
The same problem is with openSUSE. They also have fpc-2.4.2 but not complete. This 2.4.2 version in SVN includes also support for connection to MySQL 5.1 unfortunately packages from Fedora/openSUSE don't have it. Because I want to compile CQRLOG also on Ubuntu 10.04 I moved new db support to cqrlog source tree. FieldNameQuoteChars variable is redeclared again in cqrlog source code and this is not needed in newer fpc compilers versions.
