With this error message, it really is the C libs. If cabal cannot find
the headers then it says so explicitly.

Cabal does the check by making a trivial .c program and linking it
with (approximately):

gcc main.o -lpcre

If that fails then cabal declares that it cannot find the C lib. It's
possible that the lib is present but that there is some other linking
error, it's a bit tricky to distinguish without looking at the error
messages from ld.exe.

So the first thing to try is the above test, or run cabal configure
-v3 and see what error message ld reports.
