  PRAGMA

  【1.0 bulid 29 追加】
   PRAGMA <OPTIONS x> | <LDFLAGS x> | <COMPILER x> | <INCLUDE x>

   Type: statement

   Instead of passing commandline arguments to influence the behavior of
   the compiler, it is also possible to define these arguments
   programmatically. Mostly these arguments are used when embedding
   variables or library dependent structures into BaCon code. Example when
   SDL code is included in the BaCon program:

   PRAGMA LDFLAGS SDL
   PRAGMA INCLUDE SDL/SDL.h

   Example when GTK2 code is included in the BaCon program:

   PRAGMA LDFLAGS `pkg-config --cflags --libs gtk+-2.0`
   PRAGMA INCLUDE gtk-2.0/gtk/gtk.h
   PRAGMA COMPILER gcc

   Example on passing optimization parameters to the compiler:

   PRAGMA OPTIONS -O2 -s

   Multiple arguments can be passed too:

   PRAGMA LDFLAGS iup cd iupcd im
   PRAGMA INCLUDE iup.h cd.h cdiup.h im.h im_image.h
