------- Additional Comments From anh_vn_vo at yahoo dot com 2005-05-18 01:06 ------- After further checking, the run-time support was not built. In fact, running any Ada code containing Ada task triggers "failed run-time assertion : Tasking not implemented on this configuration" error message. This problem occurs even though option --enable-threads=gnat was set in the configuration. Looking around the source code, a possible bug at line 1277 of Makefile.in under subdirectory ../gcc/ada. The word cygwin32 should be changed to cygwin because only the name cygwin, in i686-pc-cygwin, was generated in the Makefile resulting from executing configure command.
