#168 Build failure on MinGW

[Jřrgen H. Seland]

configure fails on MinGW (v4.1, MSys 1.0.1) when
checking for required functions truncate and mkstmp
(line 250-253 of configure.in, 3.8.3 sources).

When this section is disabled, the make process fails
with the following error (shortened; the same error
repeats over and over again):

cc1plus.exe: warning: command line option
"-Wmissing-declarations" is valid for C/ObjC but not

This can be circumvented by modifying include/globals.h
like this:

$ diff globals-3.8.3.h globals.h
44c44,45
< #ifdef WIN32
---
> //#ifdef WIN32
> #if 0

I assume this puts dynamic linking out of commission,
but it appears to work for static libraries.
