I'm trying to install flex on my Windows computer. I have MSYS installed. I untar flex, ./configure it, but when I try to make it, I get this error:

In file included from ccl.c:34:
flexdef.h:94:19: error: regex.h: No such file or directory
In file included from ccl.c:34:

make[2]: *** [ccl.o] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2

Until recently, I've only ever installed things using an .exe, so I'm pretty confused by this. Installing bison and m4 both went smoothly, and I'm wondering why this isn't. Any ideas?
