Gnu mv -f works. # RM: Must accept an arbitrary number of space separated file # arguments, or one wildcard argument. Gnu rm works. # RMDIR: Must delete a directory and all its contents. Gnu rm -rf works. # ECHO: Must support command line redirection. Any Unix-like # shell will typically provide this, otherwise a custom version # is trivial to write. # AR: Gnu ar works. # MKDIR: Gnu mkdir works. # CHMOD: Gnu chmod works. # true: Does nothing and returns a normal successful return code. # pwd: Prints the current directory on stdout. # cd: Change directory. # # Optional: # BISON: Gnu bison works. # FLEX: Gnu flex works. # Other miscellaneous tools for obscure targets. # Suppress smart makes who think they know how to automake Yacc files .y.c: # Variables that exist for you to override. # See below for how to change them for certain systems. # Various ways of specifying flags for compilations: # CFLAGS is for the user to override to, e.g., do a bootstrap with -O2. # BOOT_CFLAGS is the value of CFLAGS to pass # to the stage2 and stage3 compilations CFLAGS = -g BOOT_CFLAGS = -O $(CFLAGS) # These exists to be overridden by the t-* files, respectively.
