When compiling htmldoc 1.9.16 from source, on Solaris 11.4.51.132.1, with gcc 12.1.0, the htmldoc/ps-pdf.cxx file fails to compile:

gmake

Upon research, I was able to compile htmldoc 2.9.15 just fine with the same configuration.

I believe this is related to the two following issues/commits: 543d6e3827cbb0e0efee186365d4754a9e3d3389

On Solaris, in /usr/include/iso/time_iso.h, the struct does not contain tm_gmtoff:

struct  tm {    /* see ctime(3) */
        int     tm_sec;
        int     tm_min;
        int     tm_hour;
        int     tm_mday;
        int     tm_mon;
        int     tm_year;
        int     tm_wday;
        int     tm_yday;
        int     tm_isdst;
};

I noticed that in the configure output, there is a line to detect whether tm_gmtoff exists, while setting HAVE_TM_GMTOFF:

checking for tm_gmtoff member in tm structure... no

I'd imagine you probably don't have a spare Solaris server to compile on, so please let me know if you need me to test compile a fix.

Thanks again for creating/maintaining a great tool!!!
