18# The AST sources use a utility called "iffe" (If FEature Exists) to probe the
19# build environment, and to generate the header files needed to build the
20# libraries and commands. In order to support cross-compilation, the
21# generated FEATURE files are bundled with gate, but a TBC target is
22# provided to re-generate them if necessary due to a change elsewhere in gate.
23#
24# NOTES:
25#
26# Only the primary compiler is used with iffe.
27#
28# We use big PIC here since pic is too small on 64-bit sparc and on 32-bit
29# it's close to the barrier.
30#
31# "-D_map_libc=1" is needed to force map.c to add a "_ast_" prefix to all
32# AST symbol names which may otherwise collide with libc.
33#
34# "-D_lib_socket=1 -lsocket -lnsl" was added to make sure ksh93 is compiled
35# with networking support enabled; the current AST build infrastructure has
36# problems with detecting networking support in illumos.
37#
38# "-D_TS_ERRNO -D_REENTRANT" are flags taken from the default OS/Net
39# build system.
