dnl  Automake "no-dependencies" is used because include file dependencies

#   - a few tests for known bad compilers

#   - choice of ABIs on suitable systems
Packit 5c3484
#   - selection of corresponding mpn search path
Packit 5c3484
#
Packit 5c3484
# After GMP specific searches and tests, the standard autoconf AC_PROG_CC is
Packit 5c3484
# called.  User selections of CC etc are respected.
Packit 5c3484
#
Packit 5c3484
# Care is taken not to use macros like AC_TRY_COMPILE during the GMP
Packit 5c3484
# pre-testing, since they of course depend on AC_PROG_CC, and also some of
Packit 5c3484
# them cache their results, which is not wanted.
Packit 5c3484
#
Packit 5c3484
# The ABI selection mechanism is unique to GMP.  All that reaches autoconf
Packit 5c3484
# is a different selection of CC/CFLAGS according to the best ABI the system
Packit 5c3484
# supports, and/or what the user selects.  Naturally the mpn assembler code
