Subject: * Makefile.in (VPATH): Add regex directory. (NM): new variable.
 (OBSOLETE_FUNCTIONS): Ditto. (NEW_FUNCTIONS): Ditto. (install-headers):
 Install regex.h. (install-man): New target. (install): Use new target.
 (DLL_OFILES): Add v8_reg* stuff. (new-cygwin1.dll): Eliminate
 stamp-cygwin-lib creation. (libcygwin.a): Remove obsolete functions from
 import lib.  Add new functions. * configure.in: Detect 'nm' tool. *
 configure: Regenerate. * cygwin.din: Export posix_reg* functions.  Eliminate
 export of v8 reg* functions.  This is now handled in object files themselves.
 * regex/*: New files. * regexp/v8_*.c: New files, renamed from non v8_
 equivalents.
