I don't have this problem (the OS is detected correctly) but -mno-cygwin
doesn't work for threaded externals (and therefore also a flext dynamic
library) because pthread definitions don't get included in the relevant
cygwin header files (as __CYGWIN__ is not defined then).
Without that flag all static versions of flext compile ok here.

MinGW works ok. I added makefiles etc. to the flext cvs folder. (working
versions to check out by tomorrow morning)

Hmmm, i don't understand. However, have a look at tomorrow's cvs makefile.

Without special tools (which ones?) linking a flext.dll currently fails
because the linker can't cope with the variables (garray_class etc.)
exported by pd.lib .
I'm happy about any ideas how to solve this
