@defmac TARGET_C99_FUNCTIONS
When this macro is nonzero, GCC will implicitly optimize @code{sin} calls into
@code{sinf} and similarly for other functions defined by C99 standard. The
default is nonzero that should be proper value for most modern systems, however
number of existing systems lacks support for these functions in the runtime so
they needs this macro to be redefined to 0.
default is zero because a number of existing systems lack support for these
functions in their runtime so this macro needs to be redefined to one on
systems that do support the C99 runtime.
