Something similar happened to me some months ago. In that case the
problem was caused by GnuWin32 header files with the same names as
Emacs' own header files. IIRC, one of those header files is regex.h

The solution is to either remove the conflicting header files from
GnuWin32 Include directory or, better, configure Emacs with

-isystemc:\GnuWin32\include

instead of

-Ic:\GnuWin32\include

This way gcc will put c:\GnuWin32\include at the end of the search
sequence used for searching header files.
