I've got an interesting problem that maybe someone out there has run across.
When building genSub with EPICS 3.14.4 and gcc 3.3 on solaris I get the
following error 

/home/wdahl/kroot/rel/if/humidity/0-0-1/include/genSubRecord.h:4382: error:
redeclaration
   of C++ built-in type `long'
/home/wdahl/kroot/rel/if/humidity/0-0-1/include/genSubRecord.h:4382: error:
parse
   error before `!' token

Line 4382 of genSubRecord.h looks like

unsigned long not; /*No. in T*/

My guess is that the "not" in that line is being translated to a "!".

Yup, according to the C++ specification section 2.5 Alternative tokens, "each alternative token behaves the same as its primary token, except for its spelling." The alternative tokens that are words are:

bitand	-> &
and	->  &&
bitor	-> |
or	-> ||
xor	-> ^
compl	-> ~
and_eq	-> &=
or_eq	-> |=
xor_eq	-> ^=
not	-> ~
not_eq	-> !=

We obviously need to reject these (and all the other C and C++ keywords which are not currently being checked for) as illegal field names. I'll put that functionality into the R3.15 tools that I'm working on.

Andy Foster will have to rename that genSub field sooner or later.
