Subject: Clean up some header files and fix compilation with MSC.
X-Git-Tag: release_1-7-2~5
X-Git-Url: https://www.ginac.de/ginac.git//ginac.git?p=ginac.git;a=commitdiff_plain;h=864d9d65c5ecd0b4fffa9162c156383fd5cb9951;hp=864d9d65c5ecd0b4fffa9162c156383fd5cb9951

Clean up some header files and fix compilation with MSC.

On MSC there is no <unistd.h>. It turns out that we need to #include <io.h>
in order to use close(3). This fixes the build failure introduced in 8305ec38.

Thanks to Jan Rheinländer for reporting this.
