I've tried it myself although have been unable to run it on anything
but texinfo.texi for the manuals I tried.
I did not see anything in teximakehtml.c about which converter was used
so I patched the code in converter_converter in converter/converter.c
which passed the CONVF_cxx_hashmap or CONVF_string_list argument to
new_converter. (Is the "string list" implementation really used by
default by texi2any as it doesn't look that way from the code?)
/* NOTE if HAVE_CXX_HASHMAP is not set, even with CONVF_cxx_hashmap
string lists will be used */
size_t converter_descriptor = new_converter (format, CONVF_cxx_hashmap);
/*
To use a string list. Slower.
size_t converter_descriptor = new_converter (format, CONVF_string_list);
*/
Times are in seconds.
