mingw32-make: *** [obj/gcc/so/libstlport.5.2.dll] Error 1

According to names it isn't 'microsoft'. You should investigate this issue (looks like it's mainly mingw or gcc + mingw problem, not STLport's).

Expected answers:

- where this symbols requested?
- where this symbols really defined?

I've checked GCC's built-in specs and found that in MinGW GCC 4.4.0 linking against shared libgcc seems to be not enough, static library should be present as well. Since -nodefaultlibs compiler/linker flag is used, both libraries should be specified on the command line manually. Currently only shared library is specified (-lgcc_s), adding static library (-lgcc) fixes the problem. The patch is trivial.

Well, the inlined patch seems to be quite unreadable... Does anybody know how to attach a file to this ticket?
