For some reason that I can't be bothered to investigate, gcc 3.3 on
my museum-grade PowerMac G5 running Mac OS X 10.3 doesn't like -lm
when compiling the output{...}end blocks in features/pty and
features/dll. The compilation fails silently. But some other
systems require the -lm for it to work.
Thankfully iffe has a syntax for trying a test repeatedly with
different flags (a.k.a. prerequisites). From 'iffe --man':
- Prereq grouping mark; prereqs before the first - are
passed to all feature tests. Subsequent groups are
attempted in left-to-right order until the first
successful group is found.
src/cmd/builtin/features/pty,
src/lib/libdll/features/dll:
- Try compiling the output{...}end block once with -lm and, if that
fails, try once without -lm before erroring out.
