Read readme.1st:

GCC is a command-line compiler, which you invoke from DOS command
line.  To compile and link a single-file C program, use a command like
this:

	gcc myfile.c -o myfile.exe -lm

The -lm links in the lib/libm.a library (trig math) if needed.  (Link
order is significant, so if you need libm.a, always put `-lm' at the
end of the command line.)

--snip--

It goes on for several more paragraphs.

The best overall command line to use for most purposes is this:

gcc -Wall -O -g -o myprog.exe myfile.c [file2.c file3.c ...] [-llibrary]

'-Wall' turns on extra warnings.  '-O' optimizes your code for size and
speed.  '-g' adds extra debugging information.  When compiling C++,
replace 'gcc' with 'gxx'.  Add libraries only to the end of the command
line.
