Thanks, will replace.

What do we want to do with the compat/regex build-time switch?

IIRC, this was only needed for 1.7 and not 1.5, and I also would
expect (without anything to back-up, so this is more a faith than
expectation) over time the "new library" would have a working regex

The situation is that Cygwin uses newlib rather than glibc, and does so for licesnsing reasons (redhat sells licenses to developers allowing closed source applications built using Cygwin). So, there must be a compelling need to fix the library - git has a simple work around, so isn't the case. Also, Cygwin has a perl regex library for those demanding more complete / correct regex solution. So, I make no prediction on when the newlib regex functions are fixed.

Related: Should we have separate settings for 1.5 and 1.7 for several variables? Conflicts I see not reflected in config.mak.uname on pu:
    trustable filemode   (1.7 has, 1.5 does not)
MMAP/Pread (1.7 pread is thread safe, 1.5 I dont think was, MMAP utility is convolved in this)
    regex - 1.7 is broken, per Ramsay 1.5 works

If you think its worth it, I'll create a patch series with the above and justifications for the different settings that I know.
