I cannot detect POSIX compliant regcomp/regexec routines.
These are required for AutoGen to work correctly.  If you have
such a library present on your system, you must specify it by
setting the LIBS environment variable, e.g., "LIBS='-lregex'".
If you do not have such a library on your system, then you should
download and install, for example, the one from:
