55667b94fb Added search path relative to running binary on Windows. 
In contrast to *IX it doesn't make much sense to add compile time defined
search paths to Windows binaries: There's no standard path like /usr/local/bin
(and there are no symbolic links to link from there to another location).

On the other hand it's (again in contrast to *IX) easy for Windows binaries
to determine their own paths. Therefore it's appropriate to make use of that
to add run time defined default search paths.

052b229f86 Replaced whole bunch for Makefiles with a single generic Makefile. 
- Targeting GNU toolchain.
- Modern dependency handling.
- Warning-free build.
- GCC option -Werror set.
- Dynamic search paths.
- Don't write into source directories.
- Easy cleanup by just removing 'wrk'.

e8964cde74 Quick fix for a problem in the OptLoad3 function. The fix isn't perfect and 
may fail for inline assembly code, but at least it's less buggy than before.

fd679d92d0 Fixed a problem: When a struct or unit was declared with a tag name, it was 
possible to use the opposite type with the tag name. That is "struct a" after
declaring "union a" and vice versa.
