Follow these steps to fix/patch kylix 3 work: 

Step 1 
Download the ilink and ilink.so patch provided by Andreas Hausladen here: 
ilinkpatch for more info on the patch go to unvclx.sourceforge.net 
To install just go to the download directory and run 
./ilinkPatch /home/yourname/kylix 

Step 2 
Download the latest 3.6 clx patch provided by Andreas Hausladen from unvclx.sourceforge.net or here. Copy or save this file to /tmp folder 
Install the patch by executing the following from the shell 

tar -jxf k3patches.20040915.tar.bz2 
/tmp/k3patches/installpatch 

Step 3 
Download and install the older compatible glibc libraries for running kylix apps from here. Save or copy it to /tmp. 
Install by runing from the shell 

rpm -i /tmp/compat-glibc-6.2-2.1.3.2.i386.rpm 
Now the patching is complete.... now to run kylix do the following 

Step 4 
export LD_ASSUME_KERNEL=2.4.21 

Step 5 
Run/Start kylix via 
/usr/local/kylix3/bin/startbcb 

Step 6 
Open your project and change your projects include directories via the project options by adding 
/usr/i386-glibc21-linux/include 
/usr/include 
as the very first include paths to that your include paths.. 
this will fix the error so that the correct "time.h" be included. 

Step 7 
Change your lib paths by adding (preferably in the beginning) 
/usr/i386-glibc21-linux/lib and 
/usr/lib 

Finally: 
Open the ThrdDemo (the c++ demo included with Kylix in the examples directory) This sample demonstrates the use of threads and different sort algorithms... (remember step 6+7 for this project). 
Compile and run/debug.... 
Congatulations!!! your have done it!!!
