Use of 'defineVar' and 'install' in .Call
Dear all,
[system and version information below]

expression, after replacement, should be:

Can you please report in greater detail how you added the files
pcre_ucp_searchfuncs.c and ucptable.c Mr. Kinney?
I have downloaded the files but I don't know where to put them, under

Thank you.
Best wishes,

...halted
Hope this is illuminating and that the 'bugs', whether it is in R or
in PCRE, can be resolved for the next release, this would be highly
appreciated. Meanwhile, any suggestions as to how I can cross-compile

Best wishes,
