I am much happier with this great start!

Simon - which compiler)s) did you use: xlc and xlfortran, or gcc/gfortran?

I have made some changes to configure(.ac) so maybe my problems are 
self-inflicted. But would be good to know what environment you are using.

Thanks for looking - and finding!!!

TRE uses liberally conversions between int and tre_cint_t apparently assuming that the latter is unsigned so conversions back to int are suitable for comparisons etc. On other platforms wint_t is unsigned so it works. Manually defining tre_cint_t to unsigned int fixes the issue.
