But my devel/amd64-gcc predates the removal of float.h from the installed devel/amd64-gcc so the following may not be as it would be in such a context: --- lib/msun__L --- /usr/src/lib/msun/src/catrigl.c:90:2: error: #error "Unsupported long double format" #error "Unsupported long double format" ^~~~~ . . . --- lib/msun__L --- /usr/src/lib/msun/src/catrigl.c: In function 'casinhl': /usr/src/lib/msun/src/catrigl.c:190:35: error: 'm_ln2' undeclared (first use in this function) w = clog_for_large_values(z) + m_ln2; ^~~~~ /usr/src/lib/msun/src/catrigl.c:190:35: note: each undeclared identifier is reported only once for each function it appears in /usr/src/lib/msun/src/catrigl.c:202:11: error: 'SQRT_6_EPSILON' undeclared (first use in this function) if (ax < SQRT_6_EPSILON / 4 && ay < SQRT_6_EPSILON / 4) ^~~~~~~~~~~~~~ /usr/src/lib/msun/src/catrigl.c: In function 'cacosl': /usr/src/lib/msun/src/catrigl.c:250:20: error: 'm_ln2' undeclared (first use in this function) ry = creall(w) + m_ln2; ^~~~~ /usr/src/lib/msun/src/catrigl.c:261:11: error: 'SQRT_6_EPSILON' undeclared (first use in this function) if (ax < SQRT_6_EPSILON / 4 && ay < SQRT_6_EPSILON / 4) ^~~~~~~~~~~~~~ In file included from /usr/src/lib/msun/src/catrigl.c:45:0: I can remove float.h and see what happens. === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)Received on Fri Jul 27 2018 - 02:06:36 UTC
