I committed a change and now it works with no differences with
all of nawk mawk gawk and original-awk (as of debian woody).

Changing to
	gsub(/@b\{/,"\\fB");
fixed it.

Mine is by default the older 2.13, as debian chooses.

This is just a gsub with an anchored substitution to replate leading
blank spaces. Probably some awk flavours ignore anchors (here "^")
in _g_sub. Changed to "sub" as suggested by Daniele Pala and
Sirio Pasquini some time ago, and it's fixed now.

Well, I am not concerned about Solaris in particular but about portability
in general. Unfortunately my HP test drive expired, so I couldn't try
their stuff (which is pretty bad, usually).

Fine. Applied.
