Perhaps the C89 standard did not allow this to occur?  If so, then this
is expected; if not, then this is probably a bug in whatever C library
the Pragmatic installation is compiled with.

If Ruby is going to be compiled on many platforms, then perhaps it
should use the strictest settings on each platform?  For gcc3, this
means using --std=c89, or perhaps -ansi -pedantic.  I doubt it would
help in this case, since gcc seems to use the same strtod for both
standards, but it might help in other cases.  Ruby doesn't seem to
compile, though, with these options; it seems to complain about _SIGMAX
not being defined.  Any ideas?

BTW, I just noticed for the first time that the configure file does some
checking for minix.  Does Ruby actually run on minix?
