I've had a look at /etc/fpc.cfg and there is mention to some defines:
- FPCAPACHE_1_3
- FPCAPACHE_2_0
Then in the fcl-web examples there is mention to:
- Apache1_3
The only one I've found is on the apr.pas on both these files:
- /usr/share/fpcsrc/2.4.0/packages/httpd20/src/apr/apr.pas
- /usr/share/fpcsrc/2.4.0/packages/httpd22/src/apr/apr.pas
So how does the compiler decide what version of APR to compile?
