Revision 1.139, Sun Sep 13 23:25:18 1998 UTC (16 years, 3 months ago) by tv
Branch: MAIN
Changes since 1.138: +14 -16 lines

Rethink the origins of LDSTATIC.  Instead, use an option NOLINKLIB, which
builds and installs only what is necessary to link and run binaries, when
the library is not externally useable.
- NOPIC: Create and link against a static library.
- PIC: Create, link against, and install a shared object.
- PIC+LDSTATIC: Create and link against a static library; create and
  install a shared object.
