CYGWIN ISSUES

1. Cygwin users may have to run dos2unix on the GMTparam.txt file before using with install_gmt.sh, depending on how they saved the output from their browser. Do this if you are not sure or don't know how to use od to check if it is a problem for you.
2. (From Cygwin's User Guide): By default, no Cygwin program can allocate more than 384 MB of memory (program and data). You should not need to change this default in most circumstances. However, if you need to use more real or virtual memory in your machine you may add an entry in either the HKEY_LOCAL_MACHINE (to change the limit for all users) or HKEY_CURRENT_USER (for just the current user) section of the registry. Add the DWORD value heap_chunk_in_mb and set it to the desired memory limit in decimal MB. It is preferred to do this in Cygwin using the regtool program included in the Cygwin package. (For more information about regtool or the other Cygwin utilities, see the Section called Cygwin Utilities in Chapter 3 or use the --help option of each utility.) You should always be careful when using regtool since damaging your system registry can result in an unusable system. This example sets memory limit to 1024 MB:

   regtool -i set /HKLM/Software/Cygnus\ Solutions/Cygwin/heap_chunk_in_mb 1024
   regtool -v list /HKLM/Software/Cygnus\ Solutions/Cygwin
