[patch] gettext-0.15, cygwin

[Charles Wilson]

The attached patch fixes two problems on cygwin:

(1) building out-of-tree fails because the gettext-tools directory in 
the source tree needs to be in the include path for the 
gettext-tools/lib and gettext-tools/src subdirectories.

(2) When building relocatable on cygwin, config.h defines DLL_VARIABLE 
as declspec(dllimport).  This is the desired behavior for the main 
libraries and non-wrapper applications, and works fine thanks to the 
*.exports magic.  However, unlike MSVC and mingw, on cygwin we also 
build the wrapper exe's.

relocwrapper.c includes config.h -- so via progname.h it gets a 
definition of the "program_name" variable that is declspec(dllimport). 
However, install-reloc builds the wrapper by directly compiling all 
relevant .c files into the wrapper -- therefore the actual symbol is 
_program_name, not __imp_program_name.

Because relocwrapper is always and only compiled by install-reloc in 
exactly the same way -- direct compilation of a list of .c's with no 
dependent librareis -- it should never need to worry about 
dllimport/dllexport issues.  So, after #including config.h but before 
#including any other headers, the following is safe and effective:

#undef DLL_VARIABLE
#define DLL_VARIABLE
