The code which causes the FTBFS is part of
/usr/include/pango-1.0/pango/pango-font.h and I'd suspect that this is
not an mssh-specific issue. (Then OTOH this should have caused quite
many FTBTS and I've found no according bug report against the pango1.0
source package. Maybe not much programs use -Wpedantic?)

Also grepping through the mssh source package code for
PANGO_GLYPH_INVALID_INPUT or PangoGlyph did not yield any result.

At least the -Wpedantic comes from mssh:

src/Makefile.am:AM_CFLAGS = -pedantic-errors -Werror -Wall -Wfatal-errors -Wwrite-strings

Nevertheless I think that a library should not cause a FTBFS due to
this compiler flag.

In case you think, this is still an mssh fault, please explain and
help me to understand why.
