Windows sets temp and tmp to windows style paths (eg
C:\Users\build\AppData\Local\Temp)
Cygwin sets TEMP and TMP to cygwin style paths (eg /tmp)

Confirming, MSVS fails to compile if both "TMP" and "tmp" are set.
The workaround is to unset TEMP and TMP on the line that invokes MSVS.
MSVS detects the Windows style "temp" and "tmp" vars and runs ok.

Having just one "TMP" var may cause problems... if TMP is set to a
cygwin style path MSVS won't work, and if TMP is set to a Windows style
path some cygwin apps might not work.

The current release implementation works ok - Cygwin apps work without
issue and MSVS works as long as you unset TEMP and TMP before invoking.
