SDL doesn't seem to use automake for its Makefile generation. Rather, it uses a Makefile.minimal and does a wildcard search of ever *.c located in specific subdirectories of src/. The Makefile.minimal defines these in the SOURCES variable.

For the most part, it could be as simple as placing the .c file into a folder already listed in SOURCES, and then re-run configure, followed by make. Make sure the header that prototypes your new functions (if any) is located in include/.
