+Regular expressions status
+Fri Oct 25 19:36:59 MEST 2002
+
+Boost 1.28 and 1.29 didn't compile on Solaris with STL 4.0, therefor
+sticked to v1.27
+
+Made compile and link regex under wntmsci9 (MSVC 6.03 with STLport 4.0)
+and unxsols3 (Sun WorkShop 6 update 1 C++ 5.2 with STLport 4.0). Failed
+on unxlngi4 (g++ 3.0.1 with glibc 2.1.1 and STLport 4.0) due to wctype (and
+maybe other wide character functions) not properly supported. Gave up due to
+time restrictions, feel free to improve.
+
+Archive Regex_Experimental.tar.gz contains RE.* files that may be used
+for further approaches. Extract and issue the command line
+
+dmake -f RE.makefile.mk
+
+Even if it compiled for all platforms, the remaining issue would be use
+of locales. The system's locale would be used, which doesn't guarantee
+that it works like intended, especially behavior could be different
+between platforms.
+
+I had a short glance at the PCRE (Perl Compatible Regular Expressions)
+available at http://www.pcre.org/, good library, but doesn't support
+Unicode. Localized 256 octets tables are created from locale
+information. Rudimentary UTF-8 support is implemented, but incomplete
+and experimental. 
+
+Hope we can solve the RE issues somehow :-/
