-l and -L are positional qualifiers.
If you are trying to use a library in a particular directory, then
the -Ldirectory must go before the -llibrary - and normally both of the
link flags would go towards the end of the command although I suspect
that part is just convention

I would suspect that this would also work:-
gcc -Wall -std=c99 -pedantic -lm -O3 -DMAXINFILE=20 \
-I/usr/local/include -static -DPCRE_STATIC \
-o extract -L/usr/local/lib -lpcre extract.c
