Sirs: Please note initially that the error indicated occurs systematically in the actual project, but it was reproduced here using a simpler demonstration case for documentation.
I might have to defer to www.kernel.org || gcc.gnu.org depending upon your comments, as I feel that it is not Cygwin-related per se and any advice at this junction is well come. It seems that world knows something about this situation that escapes me entirely... If it is the case, I am happy to offer additional contextual info upon request. As a very important observation, please note that gcc is invoked with '-fno-PIE' as one its arguments, despite the error message!
