I am trying to use some raw shell commands in my 'configure.ac' file and find that some constructs are not permitted without some care, e.g., regex classes, where 's/[^0-9]//' becomes 's/^0-9//' unless one doubles the square braces like so 's/[[^0-9]]//' in which case one of each pair is stripped away to get the desired form in the resulting 'configure' file. But that may not be the correct way to handle it.
I guess the manual is trying to tell me that implicitly by discussing the m4 processor parsing rules, but I haven't yet found an explicit warning to that effect about use of shell commands (except the warnings about portable shell programming and recomended non-use of the negated character class form). Are there more such constructs I should be on the lookout for? Have I missed somthing in the manual? Thanks. -Tom _______________________________________________ Autoconf mailing list Autoconf@gnu.org http://lists.gnu.org/mailman/listinfo/autoconf
