I tried adding the name of the file to the list of *.c files called libgomp_la_SOURCES in Makefile.am (line 34 in my GCC release), and then went to my build directory (which is a sibling to my gcc source's root directory), and entered

Thanks! But I just noticed this in the Automake manual:
"When you later change some instructions in a Makefile.am or configure.ac, the relevant part of the build system will be regenerated automatically when you execute make."
