Problem compiling in Cygwin
Hi, having trouble compiling basic irda code ported from Linux to Cygwin under Win2000.

I get this when running in traditional mode:

$ gcc -traditional irrec.c
/usr/include/sys/types.h:157: parse error
/usr/include/sys/socket.h:65: parse error
/usr/include/sys/cdefs.h:31: #error "You need a ISO C conforming compiler to use
the glibc headers"
/usr/include/sys/cdefs.h:43: parse error
/usr/include/sys/cdefs.h:122: parse error
/usr/include/sys/cdefs.h:173: parse error
/usr/include/sys/cdefs.h:182: parse error
/usr/include/sys/cdefs.h:191: parse error
/usr/include/sys/cdefs.h:205: parse error
/usr/include/sys/cdefs.h:215: parse error
/usr/include/sys/cdefs.h:226: parse error
/usr/include/sys/cdefs.h:231: parse error
/usr/include/sys/cdefs.h:238: parse error
/usr/include/sys/signal.h:168: #error You need the winsup sources or a cygwin in
stallation to compile the cygwin version of newlib.

For example Row 43 in cdefs.h: # if defined __cplusplus && __GNUC_PREREQ (2,8)
Row 122: #if __GNUC_PREREQ (2,97)

And this when running "normal" mode:

$ gcc irrec.c

This is compiling fine under Linux kernel 2.4.20 etc.

Please help?!

Please, any ideas?!

Is it somehow connected to the compiler flags?

This is C-code straight out of a Linux machine, should be the same...right?
