comparison lib/portability.h @ 1632:aafd2f28245a draft

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
When you include the posix header libgen.h, glibc #defines basename to some random other symbol name (because gnu) and this screws up nontrivial macro expansions of NEWTOY(basename), so work around it in portability.h.
