Title: fixed GCC compiler error: "lvalue required as increment operand"

Cpyhre's GCC compile error fix, as originally submitted in pull request #22. The pull request follows verbatim.

---

I made a fix to the GCC error when building under Windows:

```
gcc ../src/core/s-make.c -c -DTO_WIN32 -DREB_API -DUNICODE -O2 -I. -I../src/incl
ude/ -o objs/s-make.o
../src/core/s-make.c: In function 'Copy_OS_Str':
../src/core/s-make.c:133: error: lvalue required as increment operand
../src/core/s-make.c:141: error: lvalue required as increment operand
```

GCC version I'm using is:

```
C:\Users\cyphre>gcc -v
Using built-in specs.
Target: mingw32
Configured with: ../../gcc-4.4.1/configure --prefix=/mingw --build=mingw32 --ena

Thread model: win32
gcc version 4.4.1 (TDM-2 mingw32)
```

Please review the fix and if it looks ok to you, include in the main repository.
