Any hints on how to do that?
Trying to build using the i686-w64-mingw32-gcc cross-compiler dies
because nanosleep is missing. How to figure out what needs to be
installed to get that function?
$ ./configure --prefix=/usr/local --build=i686-pc-cygwin
--host=i686-w64-mingw32
<.. snip ..>
checking for ANSI C header files... (cached) yes
checking for library containing floor... none required
checking for library containing nanosleep... no
nanosleep() required for timing operations.
/source/iperf-3.1.4

Trying to build using the cygwin gcc compiler does because of
"conflicting types for 'iprintf'"
aside: Why would one redefine a standard routine instead of making
their own routine that calls the standard routine?? The conflicting
bit is in iperf_api.h:
/* Custom printf routine. */
int iprintf(struct iperf_test *test, const char *format, ...)
__attribute__ ((format(printf,2,3)));
In any case, how does one reconcile
int iprintf( ...
with
int _EXFUN(iprintf, ( ...
$ ./configure --prefix=/usr/local
