/* fcc/fm2/fpc
Driver for fast ACK compilers.
Derived from the C compiler driver from Minix.
You can create cc-compatible versions by compiling with
cc -O '-DFASTDIR="<this directory>"' -DF?? driver.c
where F?? is either FCC, FM2, or FPC.
Install resulting binaries in a public place (f.i. /usr/local/bin).
Suggested names: fcc, fm2, and fpc.
If you have ACK, you can create ACK-compatible versions by compiling
this file with
cc -O -DACK_BIN -I<ACK home directory>/h -DF?? driver.c
where F?? is either FCC, FPC, or FM2.
Install the resulting binaries in the EM bin directory.
Suggested names: afcc, afm2, and afpc.
The ACK compatible version afpc is not compatible with the 4th
ACK distribution, and thus is not on the tape.
