Don't worry about rxposix.h. We need only one of regex.h, rxposix.h, or
rx/rxposix.h, and it doesn't matter which one.
The problem now is that ./configure was apparently unable to find out
how to link in the 'regcomp' function. Search for 'regcomp' in
'configure.in' to see the source code for the relevant tests. Search
for 'regcomp', 'regex', and 'rx' in 'config.log' to see more detail
about what went wrong. Note that 'GUILE_NAMED_CHECK_FUNC' is defined in
'acinclude.m4'.
