#ifdef __HPUX__
// under HP-UX creating XmFontSet fails when the system locale is C and
// we're using a remote DISPLAY, presumably because HP-UX uses its own
// names for C and ISO locales (roman8 and iso8859n respectively) and so
// its Motif libraries have troubles with non-HP X server
//
// whatever the reason, the fact is that without this hack any wxMotif
// program crashes on startup because it can't create any font (HP programs
// still work but they do spit out messages about failing to create font
// sets and failing back on "fixed" font too)
//
// notice that calling setlocale() here is not enough because X(m) init
// functions call setlocale() later so we really have to change environment
