I have not but I was under the impression that if I was to compile my 
external in the current flext setup using single-release. This would imply no
use of threads and also statically linking to the .a lib as opposed to the .so.
Is this correct? If not what do I need to do to ensure I do so? Sorry
but I might have mentioned before I pretty clueless with this gcc stuff.

Should -UFLEXT_THREADS be added to my config.txt in the external
directory. 

UFLAGS += -UFLEXT_THREADS ?
Or should I ensure it is no defined. -U = undefine ?

I have edited this file so now the part which did contain the pthread
stuff looks like this
##############################################
#removed from both: -pthread
CFLAGS += -fPIC
LDFLAGS += -shared 

One question are you working from 5.0 release of flext or are you using
the head of cvs?

I will have some more time to spend on this tomorrow evening.

until the morning.
