Package: gnat-4.6
Version: 4.6.4-1
Severity: normal
On armel armhf ia64 m68k mips mipsel powerpc s390 s390x sparc, the
following scenario complains about the "cos", "sin", etc symbols being
undefined. Adding "-lm" to library_options (used at the end of the
link command) fixes the problem, but gnat should not expect the end
user to know if these functions are built in gcc or provided by an
external library.
