I am trying to build mingw in two different situations,

1. on mingw 
2. cross build from ubuntu 14 for target arm linux

In both situation I found that, some dependencies (such as regex) does not exist
in system default /usr/include. So I download regex from somewhere and build it.
Then I need to specify a custom CFLAGS for configure command such as below

./configure CFLAGS=-I/home/user1/include LDFLAGS=-L/home/user1/lib LIBS=-lregex


the configuration run successfully,then I proceed to do "make depend". However
it will report "regex.h" file not found. And I found that "mkdep" command does
not make use of the CFLAGS I provided on configure command at all. I worked
around it by create another mkdep command to wrap the existing mkdep command and
add my additional include folders and it worked.

Then next issue I found is I had to modify "portable.h" file as well. I had to
comment out  "#define socklen_t int" and add "typedef unsigned int uint32_t". I
am not sure why the portable.h is not generated correctly (this only happens on
mingw, not tested on ubuntu cross compiling ARM at all).
