I dont know specifically about the HylaFax Makefile, but inorder to 
compile anything with the mysql libraries you need a couple of things.

Somewhere, you need to include the mysql header:
#include <mysql/mysql.h>

Also, you need to add -I and -L tags to compilation so that the mysql 
libraries are included and linked against:

-L/usr/lib/mysql
-I/usr/include/mysql

Of course, these paths are site dependent.

Also, you may need to pass a couple of options to the linker with 
command line options to gcc:

-lmysqlclient
-lm
-lgcc

Hope that helps. To debug, change lines in the HylaFax makefile to echo 
gcc commands rather than execute them - then you can see what command 
line options gcc is getting, and work on adding the ones I have described.

Good Luck.
