Library man pages don't mention "-D_GNU_SOURCE" (newlib)

2020-02-08 Thread Keith Thompson
The exp10 function is a GNU extension, as the man page acknowledges. The exp10(3) man page (available if you install the "cygwin-doc" package) doesn't mention that you need to compile with "-D_GNU_SOURCE" to use it. It seems to be inordinately difficult to find this information. The corresponding

Question on pseudo console and legacy console

2020-02-08 Thread Koichi Murase
I have a question on the pseudo console mode and the legacy console mode. Question: Does it cause problems to set `disable_pcon' in the default value of the environment variable `CYGWIN'? When is the pseudo console mode recommended, and when can I use the legacy console mode? I noticed
