  ### Some "implicit declaration of function 'GCASET'" warnings (GCASET is also an apparenly equivalent  macro in sacmacros.h ...)
  # Why the strange "#ifdef NO_SACLIB_MACROS" under "Macros that are always defined"  in sacmacros.h ?
  # Could at least CGASET be moved out of that list ? ( If '#ifdef' is not a typo for '#ifndef' ...).
  ## Remain a couple of implicit declaration warnings for FPCATCH, NORMFCT and NORMLHS; fixed in the CompileScript.

Description: Computer algebra, specially on ordered fields
DescUsage: <<
  To get the elementary equivalent of a man3 page,
  use first "sdesc pattern" (with "pattern" eg "Algebraic number field"
  _ or "FPCATCH" _ ; it is not case-sensitive) to see what you are looking for,
  then grep that (those) items in %p/include/sacproto.h .
<<
DescPackaging: Installation "by hand"; there is no install target.
DescPort: <<
  Patching the linuxX86 build to apply also on darwin.
  Take care of missing headers and missing declarations.
