! av00 01-mar-02 First compile with Gnu77 compiler for windows
! (Thanks to Raymond Anderson for letting me know
! about this compiler and doing initial compilations)
! av01 14-mar-02 Var PI not used in routine GWAVE
! av02 14-mar-02 Sub SECOND already intrinsic function
! av03 15-mar-02 Multiple changes to include SOMNEC routines in nec2dx.exe
! av04 16-mar-02 Status='NEW', somehow seems not to replace existing file.
! av05 21-okt-02 Max number of loads (LOADMX) made equal to max-nr of segments.
! av06 21-okt-02 Max number of NT cards (NETMX) increased from 30 to 99
! av07 21-okt-02 Max number of EX cards (NSMAX) increased from 30 to 99
! av08 22-oct-02 Use of VSRC is uncertain, in some sources equal 10 and some
! equal 30 (=nr EX?). What should be new value ???
! av09 ?? ??
! av010 30-jan-03 Used DGJJ port of G77 compiler which delivers speed increase
! from 30 to 60% for small segment counts
! av011 04-sep-03 Logging of NetMX, NSMAX changed
! av012 29-sep-03 Enable user-specified NGF file-name.
! av013 29-sep-03 MinGW port used for both 11K segs and virtual memory usage.
! av014 09-oct-03 Max number of segs at junction/single-seg (JMAX) increased from 30 to 60
! av015 05-nov-04 BugFix: Use default NGF name when nothing specified.
! av016 09-nov-06 Official Nec2 bugfix by J.Burke, see nec-list at robomod.net
! av017 30-jan-08 VSRC (30) var also increase to netmx, see also av08
! av018 10-oct-08 av015 did not work properly in all cases.
