Hmmm...
-> cat foo.c
#define A ampersand
#define B berta
foo\+=B;
-> gcc -E foo.c
# 0 "foo.c"
# 0 "<built-in>"
# 0 "<command-line>"
# 1 "/usr/include/stdc-predef.h" 1 3 4
# 0 "<command-line>" 2
# 1 "foo.c"
foo\+=berta;
-> cat bar.c
fred\+=aaa
-> gcc -E bar.c
# 0 "bar.c"
# 0 "<built-in>"
# 0 "<command-line>"
# 1 "/usr/include/stdc-predef.h" 1 3 4
# 0 "<command-line>" 2
# 1 "bar.c"
fred\+=aaa
I do not see this problem...
