Starting cygwin with:
set CYGWIN=3Ddetect_bloda
bash --login -i

$ echo $CYGWIN
detect_bloda

Comilation aborts the same way as pasted above. There are no cygwin
warnings/errors, at least not printed to the shell. Should I look
somewhere else for bloda warnings? The documentation does not state what
cygwin will do if it detects bloda candidates.
