Previously I had problems with data(foo) and Gass and I had problems with
help(). His diagnostic was "POSIX regular expressions not available" and mine
was "invalid regular expression". Martin Maechler has no problems with Solaris
2.5 and suggested a regular expression library was needed, e.g., regex-x.xx.

Solaris 2.4 has regex.o in /usr/ccs/libgen.a and regex.h in /usr/include.
configure finds regcomp and make does not show any errors compiling and
loading. Hence their is no indication that R cannot find the appropriate
library. As an attempted solution, I tried downloading GNU regex-0.12 and
putting regex.o in src/main so that it would be available first when ld
searched for links. (character.c in main seems to be the only function calling
regcomp.) It does not alter the problem. (I am using gcc since the sun native C
compiler does not do well by R.)

Any suggestions?
