Dear Simon,

I thought you were trying to use + at the end of a variable.
I used:
fred+=aaa
and got

You can try it yourself by editing sandbox.env in the u-boot-dm/env-working tree.
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...
Would you mind actually trying it in the env file, as I suggested?
