I was able to run ./configure for epic, but when I attempt 'make'

I get:

./../include/ircaux.h:141: illegal function definition, found `)'
./../include/ircaux.h:142: syntax error, found `+'

./../include/output.h:23: syntax error, found `+'
./../include/output.h:23: illegal function definition, found `)'
cpp-precomp: warning: errors during smart preprocessing, retrying in basic mode

I've even tried adding CFLAGS="--no-cpp-precomp" but I still get the same thing...

Any suggestions?

Here's what you do:
1) cd epic*
3) ./configure
4) pico Makefile
5) search for cflags (control-w)

Change:

code:

---

CFLAGS = -g -O 

---

code:

---

CFLAGS = -g -O -no-cpp-precomp

---

6) press control-x, y, and then return to save changes.
7) type make
